Here's a photo of the insoles as they are now. I could spend two days sanding to get them as nice looking as concept64 but I don't think my feet will appreciate all that. I have great respect for those who make well finished carbon products after this. It takes a lot of time and is quite messy. There is glue, carbon dust, carbon scraps, fiber glass scraps, chemical fumes, etc. Lots of careful work. I sanded away too much in a few places and will have to live with it for now.
I ended up cutting off the toes between the metatarsal joints and the end of the toe so I couldn't feel the edge. There was no way to get these in the shoe otherwise. They are still a bit wide and require a lot of force to insert but they feel great. I will do some rides and report back.
The pair weighs 82 grams. I may make another set and use only 4 layers of carbon instead of 6. This would make the pair around 50-60 grams and make it slightly flexible. I may also consider something like extra layers on the bottom and fewer in the sides and toe area.
I'll also post pictures with the suede in.
