I purchased some christophe leather straps about a year ago and now they are pretty flimsy. The leather seems to be kind of on the thin side. I'm thinking of riveting in my own leather that would stay more rigid and I can choose my own thickness if I can find any around somewhere. I read about using shellac to stiffen leather but haven't tried it yet. I did try the water and white glue trick but it was short lived. Which brands of toe straps had thick leather?
