These have been my go-to socks for almost 8 years now. I love that they are cotton, so they absorb sweat rather than give you that slimy feel you can get from polyester. They have great support in the mid foot and fit great due to the sizing. Just the right amount of padding and exhibiting an attractive low cut below the ankles. I highly recommend these socks. I hope this is helpful.

Fit like a glove… on your feet!

Size: Large, Color: White (6-pairs)

There socks! What else can I say?! Good fit! Good feel! Good quality! A little more on the thicker than thinner side, so if you want a really thin white ankle maybe go another direction.
