They are very uncomfortable and make my lower legs swell up,I thought that these socks were non binding but it's not the case!
Hi Thomas,
We're sorry to hear that the Ultra Thin did not perform as you expected. Unfortunately the Ultra Thin does bind and is designed as more a liner or dress sock. We do make non binding socks in our Xtra Wide style. If you would like a refund or an exchange please contact us at cs1@wrightsock.com or call us at 800-654-7191. Thanks for taking the time to leave a review.

I have a wide foot and the extra space is great.
Excellent socks
I ordered the X Large crew sock. A bit tight around the foot but tolerable. However the top of the sock is much too tight, very uncomfortable.
these socks are scratchy and not comfortable
