SPD causing hot spots and numbness?

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.

Why "of course". There are other SPD pedals with bigger platforms that spread the load a bit, like these. they should help a bit. Stiffer soles would also improve things, I guess.

Stiffer soles will definitely help. The numbness is due to the uneven pressure on your feet, and a stiff sole will distribute the pressure much better. You may also want to consider loosening your shoes a little bit.

Most people don't have the strength or weight to deflect the ball area of a halfway-decent cycling shoe. The cleat bolts may be protruding, or there may be something wrong with the insole. Otherwise, it's likely caused by the shoes being too tight. Either they're strapped/laced too tightly, or you need a wider shoe.

Move your cleats all the way back.

I found that finding the best angle and front-back position is a key factor. But it is likely largely individual. What works for someone else may not be appropriate for you.

If I were you I'd work that before you spend on new shoes/pedals.

When I was going through this same issue I found some good articles on the web from some reputable sources to walk me through finding the best cleat position for me.

Look for better insoles, to better, evenly, support your feet.
