I have chronic spinal and shoulder issues and what gloves I am using do not make much difference in my hands going numb, as long as they fit properly but not tightly. I have to change positions a lot to prevent/ease hand numbness. I also take one hand at a time off of the bar and drop them to the side, and shake them around. My hands seem to do better with non-padded gloves, or at least minimal padding. The changes for the way I am gripping the bar can be very subtle, in and out, foward and back, roll a bit left and right, etc. Drop bars are much better for me.
