I'm fairly new to road cycling although i've been mountain biking for years. Problem is, i get soreness along the bottom of my feet after an hour or so on the road. The discomfort runs along the outside of the bottom of my foot from the front of the heel to underneath the outside of the arch (if that makes any sense). I'm using a pair of Sidi shoes with Look Keo pedals. The bike has been fitted professionally although the pedals and cleats I fitted myself following the manufacturers instructions. I don't reckon it's the shoes as i tried on several different brands. I do know that my feet have high arches so i've tried Superfeet yellow insoles and a pair of 'off the shelf' orthotic insoles from a podiatrist without much improvement. Has anyone come across a similar complaint and found a solution?
