Terrible Quality, fell apart
Very poor quality. Came apart after one washing. Unraveled. Would not purchase again. Wish I had not purchases the first time.

Socks
They fit okay and they're comfortable but the only problem I've been seeing is that they're starting to unravel at the toe end

My New Toeless Socks
These toeless cotton socks have been my go to socks, I have had twelve surgeries on my foot due to a car accident on my right foot. I cannot wear close toe socks as the cause swelling and pain, now I can wear these soft toeless socks with no pain or swelling. I love I have the option of three different colors as well.
