Bought these boots a couple months back for park use and I gotta say these boots rock . Very comfortable mid flex but the way Vans designed them they are mid flex but they bend well when doing presses and going into jumps/spins. They bend but still offer the support you need when hitting and landing those jumps. The boa system rocks but one thing I noticed that with the amount of padding you gotta tighten the Boa system after working the boot in through the course of the day but that minor to me. Seems like the lower boa part needs more adjustment then the upper. Overall I think the boots are great comfortable is definitely the selling point on these boots they are up there when it comes to that. One of those boots you forget you are wearing though the course of the day.
