I haven't had problems with hot spots and numbness until a few months ago. I ride with SPD pedals on all of my bikes (Mountain and Road). On my last 30 mile ride, I started feeling the numbness starting to creep in right where the pedal was (by the ball of the foot). Then my toes started to feel numb. I didn't get any blisters, but the numbness took a while to go away.
My equipment, I'm sure, is to blame. My shoes are Specialized mtb shoes that I paid $80 for at my local shop in 2006. Pedals are, of course, M540 - M737 SPD's.
I'm going to get some new shoes. I'm thinking the Specialized Expert shoes (carbon) at $175. Will the stiffer soles help alleviate this problem? Or should I spend a little less on that shoe and get some proper road shoes and pedals? I'd MUCH rather just have one pair of shoes and one pedal system. But, I'm not opposed to the road shoes if it means better results.
I'm planning to do some century rides and a double next year (on my SS), and something like this happening mid-ride could mean DNF. I'd like to avoid that, if at all possible.
Thanks for any input.
