speaking of toes.... I sometimes catch myself scrunching up my toes while I'm riding... usually in a race if I'm hanging on for dear life... like I think that digging in my toes is going to keep my in the pack or something... It's unconscious, like scrunching up your shoulders when you are stressed. I have to watch and make sure I relax my feet if I find myself doing it, otherwise I can get foot cramps.
