X large ??

Size of X large was a disappointment… I needed something around a size 12 and socks were only the same size as a 8 or 9. I wasn’t looking for a compression sock, just one that fits.

Wrightgsock Ultra Thin Quarter

These is the third pair I have bought they are great socks super soft and dry fast .great for cycling. I'm a size 10.5 and I got the XL fits great

Michael Kearns
Superb sock

I ran sockless for close to 50 years, except in really cold weather, when I wore one of the long-ago ancestors of this sock. Now, in the waning years of my running life (sigh), the bottoms of my feet have become very tender, the callus pads worn down to nothing, etc. The newest iteration of the ultra-thin is going to enable me to get a few more years out of these feet. Also worth mentioning is that they breathe incredibly well, and if I run through rain and the rain stops, chances are by the end of my run the socks will be close to dry. Magic? Seems like.

Hi Michael,

We're glad to hear that the Ultra-Thins are working well for you and hope they can keep you running a bit longer. 50 years is a long time to be a runner with or without socks so congratulations on that milestone, we are happy that Wrightsock can help you continue doing what you love for even a little longer. Thank you for taking the time to leave a review and we wish you many years of running to come.
