Ergon GA3 blue grips
These do work for taking numbness out of the palm. They have a great feel to them, very grippy. I like the marking on them to show you how to place them. I wasn't sure after using round grips, but I like them very much. Good quality.
They seem to absorb dirt easily, although it cleans off easily too.
I am very happy with the quality and feel of these grips. They help support my wrist and I have had no fatigue since getting them on.
