I haven't tested these out yet, but wanted to let people know these run large. Medium is stated for Men's 5.5-8.5. I'm an M8.5, they fit loosely (it's ~9" from toe to heel corner) so I'm afraid that they will stretch out more and be too big. Exchanging for Small and will hopefully be able to update this post with my review.
Comfortable & Great Fit overall
Great quality socks. These were manufactured for outdoor activity.
Nice fit and feel. Not warm, so perfect for Pickle Ball.
