My feet started going numb at 6-7 miles and by 12 miles I had to pull over and take off the shoes. Adjusted cleats, loosend straps, changed socks. Got fitted again, and again(LeWedges added), and again(Serotta). got orthotics and new shoes. Orthotics seemed to cure the numbness but the outside of the foot hurt much worse. adjusted cleats some more. Threw away evil orthotics as the pain was worse. Visited podiatrist who said there's nothing wrong with my feet. Went back and had the LeWedges added back to my shoes. Rode trainer for 11 miles in shop, no pain. Went riding for another 10 miles, started to feel pain on the outside of foot. Adjusted cleats as far to the outside of the shoe as possible(moves foot closer to crank). Been riding around 10-12 miles so far and can feel the numbness starting. Considering searching for new shoes but in the meantime I believe I'll shove some new insoles in there; maybe the gel kind.
I use Ultegra pedals, currently with Nike shoes. I weigh less than 160lbs. so nobody thinks carbon soles will help but if anybody can tell me otherwise I may go for it; having your feet hurt sucks.
