Nice review. Yeah, they run a little bit longer than the 7s. I'm OK with size 9, but should maybe have gone for a half size down like the playtesters.
I have played with my pair for three sessions and can only agree with the video review. Wonderful shoe.
I got plantar fasciitas while using the 7s and gave them up for Barricade boost 2017 and then the Vapor X. With the 8s my plantar fasciitas has acted up again, sadly, but it is not as bad as with the 7s. The arch suppport is simply not firm enough, I think, and the fit around the arch not snug enough. But this is a more individual issue, and perhaps due to size. During play I have no issues. The problems come afterwards. I'm going to keep using them and see if my feet settle in. Otherwise, I'll just use my custom insoles, although it is not necessary in my other tennis shoes. The insoles fit nicely in this update and does not give that severely elevated feel I hate when using the insoles otherwise.
