Very good fit and comfortable!... perhaps the most comfortable sock I've ever owned. What is also good about these socks is they are naturally antimicrobial which means you can really work and play hard and not have smelly feet after a day....or two. That comes in handy if you are hiking or working long hours! Oh...also what I think I like over similar brands is that these do not cut into the leg and leave impressions all while made in the USA!!!
