Played three straight hours of doubles in these and my feet didn't ache at all, which never happens. The grip on the court is seriously locked in when I'm lunging for kitchen dinks, and they felt broken in right out of the box.
Wore these for a three-hour session and my feet didn't ache at all, which never happens. The cushioning under the forefoot is genuinely noticeable when you're lunging at the kitchen line. Only gripe is they run a touch warm, but that's minor.
Grip on these is solid — I can cut hard to the kitchen line without sliding, which was my main worry. Only gripe is the toe box runs a touch narrow for my wide feet, so size accordingly.
