I am on my third pair of cycling shoes. The first ones I wore out, and as far as I remember I never had any problems with them. When I got my second pair I started having foot pain, sort of in my arches. I never liked those shoes and just got another pair of Sidis. (If it matters the first pair were Sidi, the second pair was not). It seem a little less, but I still have pain. It is only when I'm riding, but not every time. Never with other shoes or while I'm walking in my cycling shoes. Are they too loose, too tight? Any ideas?
