They look just like the photo...fit and feel great!
Size: Large, Color: White/Gray (6 Pairs)
No complaints on these. They fit great, are supportive cotton, and look great. I was so used to the cheap Wal-Mart-bought fruit of the loom (think) ankle socks that I had no idea what I was missing. These are thicker, made better, and feel great. They even support the back of your foot from riding against your shoes. Because they are a bit thicker, they do make my feet hotter than before...but I've adjusted the shoe I wear to allow more breathability and don't wear them for long periods anyway. I live in Texas...we wear flip flops most of the year round. :)

Love these socks! They are absorptive, comfortable, supportive, attractive & great fitting!
Size: Medium, Color: White/Gray (6 Pairs)
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.
