All 3 models are great, but I can't put the NXXT's over the 20's and 21's...based off materials alone
Speaking of the 21's, I've probably hooped in them for 25 hours total now. IMO they feel more like a upgraded version of the NXXT's. Everything about the shoe is nice, but I do kinda feel like I'm wearing a mid-top shoe when I'm playing in them. That's one of the biggest differences from the 20 to the NXXT (outside firmer cushion and materials)... they both get the job done but the 20's are more fun to play in.
And whoever took that sweaty 21 pic must've been playing in no socks lol
