Birkenstock Resoling


 Article has been moved to my blog at OhYongHao.com
 After about a month of research, despair, haggling and luck I finally am able to wear my Birkenstock's again.

Quick Rundown

You can refer to this blogpost here which has pictures and is where I got all my knowledge.  I'll simplify the steps here for those that are impatient and add my comments of things that I ran into later.

  1. Gather Materials
  2. Preheat oven to 200 degrees Fahrenheit
  3. Prepare soling material - Cut out a rough shape
  4. Clean your sandals (Optional)
  5. Place sandals in oven for 10 minutes
  6. Take sandals out and remove the sole - HOT
  7. Use an abrasive to roughen sole and sandal
  8. Add cement
  9. Let dry
  10. Put sandals back together
  11. Cure
  12. Cut off extra material

1. Gather Materials

This was probably the hardest part.  For those of you that don't like rants then you can skip down to the list of materials, but this really just infuriated me over the close shop mentality.  I don't know of any "Cobbler License" out there, and I guess most of the "Cobbler Suppliers" don't either, so they came up with a different practice, only selling to licensed medical professionals.  Nearly every store website I went to that carried Birkenstock soles fell into one of two categories.  Either they were A) closed or B) only sold to podiatrists or diabetic specialists ( I assume due to the lack of circulation in their feet a lot of diabetic specialist also second as cobblers or have cobbler friends that need to make specially designed shoes for their patients).
There were a couple of other sites, but you had to open a credit account and have a business license in order to order from them, that made it a bit more difficult than I was willing to do.  It pretty much seems like you have to already be a cobbler to purchase cobbler supplies.
Another option was purchasing from a cobbler.  One in my area wanted about $35 just for a pair of soles, or $65 to put them on for me.  I did find one website after about a week of searching, but he was hesitant to sell the remaining of his Birkenstock sheet (less than or equal to one sheet), but offered to sell his Vibrem sole sheet for $75.It was a stroke of luck that the next day I ran into a Canadian website and was able to purchase a single sheet (although the sales representative was a little surprised when I only ordered one).  There was a second site in the UK that would have been about the same price.

Here's the list of material:
  • 2 Soles - My EVA sheet is about 3'x2', but you only need enough to cover your sandals
  • Utility knife - Something that's sharp and at least 10mm long, preferably longer for cutting the soles initially if you get a sheet instead of pre-cut soles.
  • Butter knife - used to help separate the sole from the rest of the sandal.
  • Bardge Cement - Some people recommend finding the yellow can, I've only had experience with the 2 oz blue tube.
  • A Dremel - Hopefully by the time I publish this I've used one.  If you're reading this then obviously I have not.
  • 1 piece of sandpaper - Used to roughen the sole and to help remove some of the old glue
  • 1 crayon - Anything to be able to mark the outline of the sandal on the sole sheet so you know where to cut. 
  • 1 Plastic spoon - Used to apply the glue
  • 4 Rubber Bands - The more the merrier, make sure they fit the width of your sandal and the stronger the better.
  • Aluminum Foil - I used this under the sandals while I baked them in the oven to catch any dirt that might fall.
  • Toothbrush - Use an old one or a new one, that's up to you, but I don't recommend using it the next day to brush your teeth.
  • Ovenmit - 200F might sound low for an oven, but it's hot on your hands.
That should do it, if you bothered to read my rant you might find the soles are the hardest piece to come by, everything else was relatively easy to obtain.

2. Preheat Oven to 200F

You might want to take some considerations for your oven and the food that you'll cook in it later.  I opted to place a sheet of aluminum foil under my sandals to catch any dirt.  Also, after removing my soles I also used the self-clean feature to burn everything else that might have been left and turned on the stove fan and opened a couple of windows.  There wasn't very much smell the next day.

3. Prepare Soling Material

While the oven is heating you can begin other preparations as time permits.  You'll need a place to cut, either a utility bench or a cutting board will due.
First you'll want to place the sandals on the material, being the scrooge that I am I tested out various patterns that would yield the most soles and opted for the L and R facing opposite directions next to each other.  I estimated I could make about 10 pairs, or 20 soles, this way.  Try to outline a little larger than the actual sandal, it's easier to cut away extra material than it is to glue more on.
The material can be a little tough, but I found that with a utility knife making a shallow sketch and following it over and over works out nicely and is easier to control.  There is a grain to the material, so I recommend making the first cut along the grain and then you can bend the loose material down while doing multiple cuts against the grain, this will make it easier to hand the second edge.

4. Clean Your Sandals

This step isn't absolutely necessary but I believe it is beneficial.  One thing I tried to do was soak the rest of the sandal to help protect it from any heat damage done by the oven.  It may have been a good idea to add lotion to the leather beforehand, but having not done so I can't say that the results would have been any better.  I did notice that after baking my leather is darker next to my unbaked sandal.

5. Place Sandals in Oven for 10 Minutes

You can go ahead and place your sandals in the oven and set a timer.  I placed a sheet of aluminum foil directly underneath mine to prevent any dirt from falling down.  It would also be a good idea to turn on the stove's overhead fan and to open a couple of windows nearby unless you love the smell of burnt rubber.  This rubber is going to shrink, and that's how you know it's working.
During this time you might want to prepare your workstation for the next step.  You'll want to be able to work quick once your sandals are out so you don't have to bake them twice.  You'll need your butter knife or whatever you've decided to help with prying the sole off.  It's going to come off easily, and the knife may not be necessary, but it's better to have something at hand than to run and get it while racing against the cooling clock.  I'd also recommend having the utility knife at hand which you can use to "cut" the strands of adhesive while prying the sole off.

6. Take Sandals Out and Remove the Soles - HOT

Now the time has come to see if we really are crazy like my wife kept asserting.  Although we're used to running our ovens at 350F and higher 200F is nearly hot enough to boil water, and definitely hot enough to give your skin a burning sensation.  Before you remove them from the oven you should have already prepared your workspace and have all tools that are needed nearby, namely the butter knife or other flat edge to help in prying the sole from the rest of the sandal.
Remember that your sandal is delicate and you don't want to ruin the base between the cork and the sole, you should have noticed that the sole has shrunk while in the oven, time is of the essence, you want to work fast, but don't be hasty.  Slowly peel back the sole and you can use the butter knife to encourage it a little bit by placing it near where the sole is now separating from the sandal.  If you're taking too long it may get harder towards the heel.  If peeling from heel to toe it may get harder towards the toe.

7. Use an Abrasive to Roughen Sole and Sandal

This step may or may not be needed, if someone could leave a comment arguing either way I'll incorporate it into any edits I do to this page.  For me, my experience was not really having a good thing to roughen either the sandal nor the sole, whatever I did try using didn't seem to do anything.  You can probably just skip this step

8. Add Cement

You should have already prepped your soling material by cutting it into roughly the shape of your sandal or at least in a large enough rectangle that you can comfortably place the sandal on and not be lacking in material.
I applied the cement by first doing a zig-zag pattern from the toe to the heel and then using a plastic spoon to smooth out the cement.  Make sure that you get every inch of your sandal, especially the outer edge.
Once the sandal has been done you can now apply the same to the soling material.  Do a zig-zag pattern and spread with the spoon, make sure that it extends past where you think your sandal will be to ensure that your entire sandal will adhere together.
DO NOT put the sandal and soling material together right away!

9. Let Dry

Follow the directions on the box or bottle for how long you should wait before pressing the two pieces together.  Mine was around 15-20 minutes.  I set a timer and started reading a book.

10. Put the Sandals Together

After having waited the appropriate amount of time I then went about putting the two pieces together.  This must be done with great care because once you have let the cement dry slightly it becomes extremely adhesive and once in touch with itself it will be nearly impossible to let go, this is the primary reason for using a piece of soling material that has not been precisely cut, therefore allowing you a little wiggle room if you happen to be slightly crooked.
For me I started with the corner, if you can call it that, where the straight outside edge curves to form the toe area by eyeing the straight edge and slowly put them together.  I'd like to emphasize again that this is extremely adhesive and you don't really get a second try.

11. Cure

After this is all said and done you now have a successfully put a new sole on your old sandal.  But don't start celebrating yet by wearing them around, you still need to allow the adhesive to cure for the next couple of hours, preferably all not.  It is a good idea to use some sort of weight to keep the sole and sandal together from toe to heel.  For me I used the leaves of my table although I feel that it wasn't quite adequate enough at distributing the weight.

12. Cut Off Extra Material

Now that the adhesive has cured the sandal should be fit for wear outside the house, but wait!  One final step, we have to cut off any extra material that is left.  I used a utility knife for this.  For the most part I just cut off in large chunks with straight lines.  There was some fine work to be done with the heel and toe, also I could have gotten closer on the sides if I had some sort of sanding tool like a dremel.  I haven't actually done this yet, I've been content enough with just having cut off any protruding areas with the utility knife.

Partial Sole Replacement

After this I realized that the bit I cut off from the heel was actually about the same amount I needed if I were to attempt a partial sole replacement on my left sandal.  This was a similar process but instead of baking in the oven which would ruin the entire sole, I used the stovetop to apply direct and more localized heat after having scored the sole first.  A spoon or some other wedge is extremely handy here.  Once the portion of the sole you do not want is removed follow steps 7 through 12 just like for a full sole replacement.

Conclusion

A single sheet seems to have enough material to do at least 18 full sole replacements with about 18 heel replacements.  Seeing how this took me about 4 months to wear through one side while doing what I would consider a light amount of walking this should last me around 3-6 years.  But since learning partial sole replacement techniques I may be able to extend that out much further.
It's up to each person to decide whether to enlist the service of a cobbler or not.  For me I felt that the price wasn't worth it, seeing how a half sole replacements is $10, so for the one and a half soles I did it would have been $30 a probably a bit more professional looking than mine.  The Birkenstock is probably one of the easiest to resole though, and if you have the extra time and can find some soling material I feel that it was well worth it.

I Voted For Gary Johnson

For the past six years I have really been out of politics, never really involved before.  I was living in a different country at the time, and although I got my absentee ballot and voted, I never really took the time to care about everything that I was voting for.
Somehow this year was different.  I started off by watching the Republican Primary debates online.  It was during these debates that I first heard Ron Paul speak.  The more I heard him speak, the more I thought about the issues he mentioned, the more I realized that I too wanted personal liberty, freedom from oppressive taxes, a great desire for a non-intervention foreign policy.

President

Although Gary Johnson didn't do as well as we had hopped I still don't regret voting for him.  Voting for Gary Johnson gives me the right to say "I didn't vote for that" when Obama continues his fight against civil liberties, or sends more troops overseas to be maimed or slaughtered, or when he sends FBI agents to raid marijuana facilities in Washington or Colorado.
As I have learned more of what "Republicans" stand for I have found that I am not even close.  How can I associate with those that believe that pro-choice is the same as pro-abortion.  For those of you who think that please read this very well written article: How I Lost Faith in the “Pro-Life” Movement. What about gay marriage?  Should we not be free to choose?  They aren't going to force me to be gay.  How about marijuana, education, or a non-interventionist philosophy to foreign policy?  When I first heard Gary Johnson speak I was a little weary of him, but I found out that all the things that I believed to be true he did too.  I think we are all libertarian at heart.

I-502

Going along this trend for liberty I also voted for Washington's Marijuana legalization initiative I-502.  Even though chances are that I probably won't be one using marijuana, it at least gives me the choice if I want to self prescribe anti-depression or pain medication.  Why should I have to seek Western Medicine for all my ailments?  Does not even the Bible declare all herbs fit for man?  But let us not derive all our knowledge from holy books that are held true by some, what does science tell us?  We'll know within the next decade as UW and WSU begin to receive funds from I-502 specifically for this purpose.
What was strange about the Washington marijuana initiative was that a lot of the opponents were from the pro-pot movement.  A lot said it was too restrictive, especially with the DUI portion of the law.  What I feel is that it is a step in the right direction, and once now it is legalized we can work on correcting the law, but at least mere possession will no longer be a crime, use neither as long as you don't drive.  In the decade to come we will see this leash loosened.

R-74

This, above all others, has been a hot topic of debate.  Referendum 74 is concerning same-sex marriage.  Although personally myself I believe marriage should be between a man and a woman I am not going to force others to follow my own beliefs.  The availability of marriage has not deterred those that have same-sex attraction from seeking out to be, in every way legally possible, a spouse to someone the love.  If you happen to believe that this is immoral try to think of the atrocities that have happened to fight against homosexuality.  Alan Turing, key principle in World War II in deciphering the Germans encryption, committed suicide rather than be chemically castrated.  With this so-called defence of marriage, have us, heterosexuals, really done so much to deserve the sole title of marriage?  How much divorce is there?  How many abusive relationships are there?  How many choose not even to get married?
Despite my personal beliefs in marriage I have an even firmer belief in liberty.  I believe that the force of law has no power to bestow morality upon a people, but that morality comes from a far different place than law.  Even our scientists agree on this and declare that morality is far more intuitive than we may believe.
I could no longer support this kind of discrimination, who am I to force my beliefs on others.  Is it not much more of a testament of love or devotion to choose rather than to be forced?  Therefore I voted Yes on R-74.

Conclusion

Hopefully some of those who read this may have their conciousness raised and begin to understand what the fight is really about.  It is about control, self control vs government control.  It is about the freedom to choose for ourselves this day who we will serve.  In each measure I looked at I thought of which one gives me my own choice and which one forces my choice on others and that is how I voted. May we all go forward on this road towards liberty, which has been slowly evolving throughout the ages as those rare individuals are willing to put forth these ideas and to encourage others to choose for themselves.
