I recently wore out a pair of Pearl Izumi's from this year. They have that set of little chunks of padding in the "correct" places. I dug out a still new pair of gloves that had a very thin padding all over the typical areas. Hand tingling went way down. I think the chunks were just turning into pressure points instead of bridging the nerves.

That said, I've always had problems with hand numbness and I really had an epiphany this year when I studied the anatomy and understood where the nerves go. Now, I no longer pressure those areas - I changed how I hold the bars, and I have very little numbness at all.

This is a good link that helps a ton. I'm willing to say that it was the single best post I've read on BF.

This whole thread is useful too.

What it really comes down to is to put pressure on your hands where you were intended to pressure them. It's basically the heel of the hand (where you feel the pressure when you do pushups) and the "karate chop" side of your hand. Don't let the hoods pressure the crook between your thumb and index finger. Do that, and unless you have issues with tingly hands when doing pushups, you should be pretty much numbness free.
