Great running socks!

"So far, these running socks have been wonderful. I've only run in dry weather, so I am hoping they perform well in the rain, too. Customer service online was very helpful. The order was delivered quickly, too."

These socks are legit!

"These socks aren't just comfortable, they fit exactly the way I'd expect a running sock to fit: snug but not overly tight & gripping your feet in all the typical spots where you'd get a hot spot. I had never bought this brand of sock before. I'd only ever used Balega, Pacas, Dart Tough or Smart Wool. I'm a convert! CEP Running socks will be my new go-to sock. They're true to size & feel so good. Highly recommend!"

Comfort for the foot but

"Very comfortable But very expensive !!!! For no reason"

— zammy m. (5/5)

Very comfortable but sizing seems off. Great moisture wicking but can't prevent all blisters.

"Very comfortable but sizing seems off. The socks have held up well through months of training runs and during a half marathon. I bought my correct size but they still seem too tight. I'm guessing they shouldn't be too loose in order to avoid blisters but they still seem a little too tight. I do feel like the moisture wicking is there but I still got a blister somewhere around 8+ mile runs."
