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.

Comfortable athletic sock
Color: White/Halo Gray Assorted Locked-in Fit, Size: Medium
Love these socks. Neutral enough colors to pair with tennis shoes for daily wear but still a fun pattern. Comfortable, and stay in place without slipping down. Fit true to size.
