I had been experiencing numbness in my hands and fingers, while also traveling up my arms. After a proper fit, the numbness in my arms became better, but still bothered my hands and fingers a bit. I tried the Pearl Izumi PRO gel gloves on a 35 mile ride and numbness never entered the pictured. It didnt dawn on me until later that I never had to move around or shake my arms to get the circulation back. From that point, I was sold and will not ride 10 miles without them. Great !!!
