I Crossfit in these shoes five times a week, and I love them. My feet always feel great. These shoes can stand up to anything in a WOD. I like them for running short distances as well. I have flat feet and these shoes have helped make my feet stronger. I highly recommend them to any Crossfitter or someone wanting a barefoot trainer. I wear them with thin cotton socks or those little no-show socks. They work great with either. I haven't used them sockless, but that's what they're made for, so I'm sure they'd be great.
