I got a chance to play ball in my BHM's for an hour and a half last night. I echo a lot of comments made by reviewers online: great traction, kind of stiff cushioning, great lockdown fit, unique heel fit. One thing I thought was unique however, was how well the shoes fit with an ankle brace on.
I've had numerous severe ankle sprains in my life, and I'm at a point in my life where I can't be on crutches for a week due to work/family/etc. I have a lot of Nike's that fit great when worn with just socks, but would be an absolute pain with an ankle brace. While I think in terms of overall performance I still may prefer the Hyperdunks from a few years ago, the fit of these shoes with the brace on is something I just haven't seen in any other Mid/Hightop shoe so far.
Definitely a keeper in my book.
