My brother used to work in Ergonomcs and Human Factors, and he mentioned to me that gloves frequently exacerbate problems, for exactly that reason - you don't get the tactile feedback, so you grip harder.

I wear gloves no matter what temp, but I only wear unpadded ones. Every padded glove I've ever worn hurt worse than no gloves at all. Setting the bike up properly works, too. I'm currently working on getting the fit just right on a bike I recently acquired, and little things like a small adjustment in saddle angle, or saddle setback, make big differences in how much pressure is on the hands.
