Working in hospitals, laboratories, constantly standing, it was imperative to have closed shoes, comfortable, lightweight, anti perspirant and easily washable, it's done! And as a bonus I take significantly less power shots by touching metal objects, our blouses being fairly static. They carve a little big it took me to do an exchange, I am rather of 38-39 in basketball and there I had to take 37-38. Similarly I do not regret having chosen the model with vents, I think without that I would have transpired inside. Enough anti slip but be careful on wet surfaces. I am very satisfied with my purchase.
