I've made my shims from Lexan, and will head to the fastener store to track down some longer screws. I made an impression of the heel, and poured acrylic into it and allowed it to cure. Trimmed it down to the appropriate height. Now I will attach to the existing heel, and then do the same for the toe end of the shoe. Wont get a chance to work on it this weekend, but I'll keep going. Might just make one shim at the correct thickness once I'm all done, and have verified my work.
Shoe shops are funny.they won't add anything to your shoe unless you have a prescription. It's my shoe. Who the hell would want to alter their shoe and cause themselves grief? i dunno.
I also considered different crank lengths, but, another expensive option that I just didn't want to endure. I'm not cheap. I just choose to spend on other things. I can also ride my SPD's on the platform side and then not worry about any of this! I just wanted to gain the efficiency of clip less pedals-although I can't say as of yet that I have physically or mentally seen an advantage.
