There are a few reasons I've purchased so many gloves over the years - more than half the gloves in this collection are over 3 years old. The first reason is because I rotate my gloves every workout. I hate working out in damp gloves and my hands sweat a LOT - they weren't drying out between workouts no matter what I did (glove dogs, dryer sheets, you name it). This actually worked out to 2 pairs per workout - 1 for bags/mitts, 1 for sparring. The second reason I have bought so many gloves is because I have kind of weird hands for boxing: small wrists, wide at the base of the thumb, kind of narrow at the knuckles, with long slender fingers. A lot of gloves just don't fit me, even after being broken in. It was a long learning process to find gloves that were comfortable. A lot of the gloves in that picture I don't actually use (4): -the shevlin lace ups - coz i hate dealing with laces and I don't always like old school gloves. -both pairs of top contenders - they are loaner gloves for some of the kids that were showing up to my old gym with no equipment. -the ultimate classics - I've had them something like 7 or 8 years and no amount of clorox, lysol, or fabreeze has been able to kill the smell. Some of the gloves I don't use that often (4): -the American Standups - they're WAY hard for sparring and not too padded for the bag. I save them for people I want to hurt. -the shevlins (velcro & bag mitts) - old school gloves have their drawbacks, so I'll go periods where I don't use them. -the Grants - I've done a lot to try to get some use out of these gloves. The pocket is very long, with space between my knuckles & the padding. The padding is pretty hard for sparring. I HATE dealing with laces and squeezing my hands into these things is particularly troublesome. I picked up knuckle guards and bungee laces, but they're still not to a point where I'll get a bunch of use. Used them last night and if I can't find a way to make them easier to slip on I won't be using them much anymore.
