The best
Size: 9-11, Color: Black
Seriously the best non slip low cut socks you can find. They stay in place all day and I love the fabric. They are thin which I prefer. These are really the only socks I wear.

Great socks for the price!
Size: 6-10, Color: Black, Size: 6-10, Color: Black
I love these socks, they are perfect no shows but the material is thick enough for toes not too go thru. The grip is perfect and keeps the sock in place all day. I would definitely order true to size as the fit was perfect. I was surprised to find these socks at the price I did, especially when I got the socks in both black and white.

Best non-slip no show sock!
Size: 6-10, Color: Black
I love these socks! I wear them mostly with my slip on vans. The are thin so your feet can breathe (I hate thick socks). They have a grip on the heal so that they don't slip off of your feet, and it actually works! My only negative about these socks would be that if you have bigger than a size 8 foot, I would not purchase them because they do run a bit small. I wear a size 7 and they fit perfectly! They do look very tiny upon unpacking, but they stretch to the according size. I would also recommend letting them air dry after washing them and not putting them in the dryer. The first pair I purchased, I made the mistake of drying them and they shrank to an unbelievably small size. I've had my second set of socks for over 4 months now and have not had any problems since Ive been air drying them. I have not encountered any problems with them tearing as other have stated. Even though these are thin socks, they seem to be made quite well in my opinion.

I buy these again and again through the years!
Size: Medium, Color: Austin Brown Assorted (6-pairs)
Love these. After a year or two I wear holes in the bottoms because I wear them so much. Worth the little bit higher price because of the fit and comfort. Love how they are truly no show

Good quality but tight on toes
Size: 6-10, Color: White/Assorted
These are great socks that stay in place, but they scrunch my toes together like crazy. My feet are normal width. When I first started wearing them I noticed my feet would ache after an hour or two.
