played in these today for a rec league game where our team got destroyed by a dude that was 6'6" playing in a D4 league. didn't care about the game much since it was such a farce that the league allowed him to play in our division. I'm the biggest dude on our team and i'm only 6' and 205.
the shoe tho was amazing! the floor was fairly clean and the traction was great just like the XX9. cushion wise, you can feel the forefoot zoom, but i think the xx9 has a better response. The heel has more cushion than the xx9 and felt softer once i started running around. The upper however wasn't as flexible as the xx9, but it was still comfortable although a little narrow if you got a wide foot. i was able to get used to it pretty quick and no hot point at any time. The lock down did felt a little weird tho. The insoles are thick ortholite, so they're pretty comfortable. The heel to toe transition was not as smooth as the xx9, but definitely a lot better than the xx8.
personally, i would rank these higher than the xx8, but less than the xx9. at the price point of what you can find these for, these are the best shoe out of JB this year for sure.
