I held off buying these for a long time, but I finally indulged. And they are fabulous! The sole is grippy, and the upper stretches around the foot without stretching out. Compared to Vionics, the arch support is mediocre. But it's not bad. I am in between sizes, and I went for the smaller size this time. They are the tiniest bit too short for my foot, but I think the larger size would have been far too large. Now I'm just wondering what color I should get next ...
