Went and checked these out today....a couple of takeaways:
1) The floor model was messed up, the lace mech wouldn’t tighten down no matter what I did, to me it looked broken as I heared the mech tightening and clicking yet the laces stayed loose.
2) I tried on a 10.5 and the left shoe fit nice and snug and when I tightened it man oh man did it crank down, the right wouldn’t get nearly as tight and my heel was slipping out, I asked for a different size 10.5 right shoe and by one fit wayyyy better and cranked down just as tight as the left.
My opinion would be to try these on if at all possible to make sure you don’t get a faulty mechanism.
