I was experiencing serious sporadic numbness and didn't know why. I'd try loosening my grip... releasing the handlebar w/one hand and wriggling it around (uhm... the hand... not the handlebar! LOL!!!)... doing shorter rides... etc. Nothing was helping. Finally I did some internet searching and decided that perhaps the gloves (Pearl Izumi gel) were the culprit. I happened upon the Spenco Ironman Elite T.2 ladies gloves and read where they help by not compressing the carpal tunnel so numbness doesn't happen. I thought perhaps it was all hype but I found several BNWT pairs on ebay for half the price of retail so I figured it was worth a try. They arrived last week and I wore them for my metric-century ride this past weekend and I can honestly say I experienced NO NUMBNESS WHATSOEVER... during/after a 62 mile ride!
These gloves made a huge difference and I am so glad I gave them a try
