Yeah, they're socks- but they're pretty cool socks. In terms of minimal socks, these are by far my favorite. They are very minimal, which means you can wear them with a variety of shoes and they're still no-show. Plus they have a patch in the heel to keep it in place, so it's not constantly rubbing and being pulled down in your shoe. In regards to sizing, I wear a 7.0-7.5 street shoe, and got the size 7-9. They fit me fine, but I'm not really sure how comfortable they would be if I had any bigger feet- I feel like they might run a tad small. Overall, great casual sock!
