The Gamma Force are comfortable and give off a little sleeker vibe than the AF1's. The slight platform gives a nice look (and some added height :)), and the profile feels more classic like a dunk.
They were purchased for my wife and she likes the fit, feel, and style. This particular black colorway was a bit of a swing and miss, though. It lacked some of the pops of contrast as others and looked more institutional, like it would match a work uniform or something.
She was going to try them with a contrasting lace instead of the black laces that came with them. That might elevate the look.
