I used to abstain from grinding since I feared unintentionally knicking my knuckles. Presently I can grind extremely quick without stressing. I thought I requested the Medium Size, yet they sent the "Huge" which was alright. I have extensive hands for a lady ( about a size 7) . These had a lot of room These Large gloves are 9 crawls from the center finger as far as possible of the sleeve (8 creeps from center finger to the wrist. estimation under for finger to under pinkie finger is 4 inches lying level. Remember, they are stretchy so men will have a lot of space to round them out in fingers and palm.(My palm is 3 inches X 4 1/2 - long and thin however they don't fit free or loose.) Most ladies would need to get measure "Medium". In the event that a man had fat fingers, he would have a lot of space for extension with the "Huge".
