I LOVE THESE!
I bought the Womens Size 8-11 & I wear an 8.5
These socks are very thin, but let me explain why I love everything about them...
I had to mow my Grampas lawn yesterday & I wore these...
1. My feet were able to BREATHE because of the thinness so there was 0 SWEAT
2. They did NOT roll down below my heel & only cover the front 1/2 of my foot which seems so happen a lot with ankle socks (which is the reason I was a bit nervous buying these)
- What helps hold them up is a small patch of silicon on the inside heel part of the sock
3. Although they are thin, they held up great! I had to mow a big yard, then rake up all the cut grass, after that I went & trimmed the weeds around the house & fence

Im definitely buying more since I ALWAYS wear socks & shoes!
