Great socks
Color: Black/Assorted, Size: 6-10
These socks lasted me a while and are comfortable and don't ride down like some of my others as much

Will last a good while despite not being overly thick.
Color: Black/Assorted, Size: 6-10
I purchased these socks about 14 months ago and I use them regularly with maybe five other pairs of socks made by a different brand. No holes so far. I used to buy Hanes and they barely lasted a week before I had to throw a pair of them out. I still use all six of these socks (assuming I can find them!) I often walk outside on my cement patio or tiptoe through the grass in socks so I am a little tough on them I guess you could say. I'm also very active. I don't exercise at a gym and thus don't use them in tennis shoes but walk most of the day when at home. I run around in my yard doing yard work and gardening. I also have worn them regularly at work while walking around in my steel toed shoes (which rub) and they somehow lived through that. They still look fine: no discoloration or weak spots in the heel which is usually the first sign of wear for me. They are comfortable too. I don't feel any line at the toes and they don't rub or fit too tight in any way. I love the height of these, they are so short that they slip down in your shoe but not overly tall (I don't like the look and feel of tall socks). They are also lightweight and very breathable. So great quality for the price. I'd recommend and I will likely buy the same brand in the future.

Excellent, sturdy socks
Color: White/Assorted, Size: 6-10
These socks are a little pricey, but they're thick and well-made. I also love the little pops of color on top. I got a set at a local sports store and was so impressed that I immediately got another off Amazon. Two years later, I still have all twelve pairs, and they're as comfy and good-looking as they were on day one. The cheaper socks I bought previously have become thin, cold, and holey.

Pretty good
Color: Rebel Pink Assorted Locked-in Fit, Size: Medium
Quality seems good, but different colors seem to be different sizes. The whitish ones fit fine, but the colored ones seem a tad shorter.

soft, comfortable, stretchy
Color: Black/Pink Assorted Locked-in Fit, Size: Medium
Seems like some high quality, lightweight socks. Very pleased with my purchase. They are very soft, they fit just right, and the material is somewhat stretchy.
