depending on how far you're riding - why not try one of those Hot Pad thingys! (wasn't That helpful) You can buy them at like REI or sports stores. Ya know - the things that have some type of gel or something heat reactive in them? (help me out here girls - I'm really struggling!) Denise wears them between her toe covers and shoes. Anyway, you could try putting that over the plate under your foot and see if that help.!
