Okay, here's my update after abut 2 hours of on court time.
The cushioning is amazing for people who like to feel that little bounce. You feel it about mid heel and mid forefoot (just under the toes). I didn't lose as much court feel as I thought I would. I was doing a lot of hard cutting and the transition from forefoot to toes was really good. Gave me a slight boost.
I thought the use of hyperfuse was going to take away from the comfort of the shoe, but it felt very pliable on the move. I think once I work the mesh in a bit, it'll be even better. It plays more like a low cut shoe. The sock liner didn't get in the way at all. My favourite part is it's a light shoe but it feels extremely secure around my foot. Great fit for me.
The breathability was okay. No complaints. Running a lot, didn't get very sweaty. Not incredible, but no issues at all either.
I would say the traction could have been done a little better. It's good, don't get me wrong. I was playing on a pretty dusty court and didn't wipe once. But you may slip if you're doing a lot of lighter movement. I'm not really complaining about it, but they did so much so well where if they put the Kyrie 2 traction with this setup and even priced it higher than the Kyrie's, I'd still buy the Hyperrev's. Shoe of the year so far, haha.
Honestly, it was an enjoyable experience overall. Felt quick and thought I could jump higher. If you want to play ball in them, go TTS. If you're going to use them as a casual shoe or have SUPER wide feet (mine are slightly above average width), I'd go up half a size. I still liked the zoom setup on the originals better, but I think overall I'd rather play in these because of the better security, traction and fit. They're going to be in my gym bag for the next month at least.
I can't wait to hear what real ballers have to say about them.
