Exactly what they look like! They fit great, have amazing support and grip. I’m usually between a women’s US 7-8 depending on the type of shoe. I have a skinnier foot and I ordered a 7.5 and they fit perfect. I wore them for a week straight while working and never got blisters. They are also very warm on cooler days.
