Is there anyone else out there that has continuous numbness in the balls of your feet? I still have sensation, but it feels like I got a shot of Novocaine in the balls of my feet. I really don't notice the numbness while riding. It is when I am off the bike that I notice it. This has been coming on for several years. A peripheral vascular test last week ruled out any circulation or diabetes problems. My Internal Medicine doc (long distance rider too) thinks it is neural damage caused by riding a lot of miles for a lot of years. There is not much that can be done about it other than to live with it. I will be seeing a Podiatrist next week to get another opinion, but I'm not sure if he can do anything about it other than to validate my IM docs opinion.
My shoes are Sidi Genius 5 Pro Carbon Mega's with a custom insole insert. They are two years old. I have no problems with the shoes being too tight, even riding for 4-5 hours in 95-100º+ days.
I'm thinking that I could go to a stiffer sole shoe, like the Sidi 5 Carbon, to dissipate the pedal pressure a little bit more. They are considerably stiffer than my 5 Pro's.

Any thoughts, ideas or recommendations out there?
