Huh.. thanks for the replies.

I was just wondering for a few reasons:

1) my feet get cramps when i have my shoes on tight but when i loosen them sp they don't cramp then they feel too loose

2) maybe sidi's will help

3) i get to buy something else cycling

4) i currently have mtb pedals. thinking i can try road pedals for spin class to see if maybe the wider platforms also help since the cramps happen on the outside edge of my feet.

fyi: i get these cramps with other sports as well, most notably skiing (cross country to down hill). i don't ski anymore tho.
