All sporting goods stores have supplements: these gloves are usually used for fitness. It is also possible that the place where the opponent's protection will wear is the kind of equipment that I mainly practice holding above my palm and below my fingers. Are you sure the gloves won't grind when you use half your palm? Answer: No! Unless you hold the wall and do pull-ups like me, there will be cocoons on your fingers, but you use those semi-gloves to hold the equipment, which is cheap! Supplement: if you want a better quality, buy that leather one. But I think the sponge is very soft and good, and it feels good, and it absorbs sweat and is not slippery!
