I switched from Nike Air Visi-Pros which were tearing my feet up on a regular basis. The Hyperdunks have not given me a single blister and didn't require any breaking in.
The grip is decent, but there is no satisfying squeak. I like my sneaks to squeak on the court. It gives me confidence they're doing their job properly. But squeak or no squeak, I can only recall one slip in about 10 games so they definitely do grip.
I got the all-white version. And for a game or two, they looked incredible. But 10 games in; after they've been jumped on and worn on dusty practice courts, they look filthy. I've tried to clean them up a bit but they're still grubby. So with this, I wish I'd gone for a darker colourway purely for vanity reasons.
The shoe still gets a solid 9/10 from me.
