Actually I had a cobbler here in town cut me some custom toe straps. I showed him an old toe strap, and he cut a few pieces of scrap leather for me. It was really cheap, and he even riveted the buckle on. The cobbler was a nice Sicilian man, and he knew a little about bikes!
Granted its not any laminated leather but i've never had a problem with straight leather toe straps...
I've been riding a pair of 20+ year old single leather non laminated toe straps, and they're fine!
