Nice.
Size: Medium, Color: Prime Pink/White Assorted
These were great quality and perfect fit. They held up. Under Armour seems to make the better quality socks than others.

Perfect Fit and Versatile for All-Day Wear
Size: Small, Color: White/Cerise Assorted
I absolutely love these socks! Though they're technically kid-sized, they fit my size 5-6 women's feet perfectly and are incredibly versatile. I wear them for workouts, casual outfits, and pretty much all the time. They’re reliable, well-fitting, and comfortable throughout the day. The quality is excellent, and they hold up well even with frequent use. If you’re looking for socks that combine great fit with durability and style, these are definitely a top pick!

Great socks
Size: Medium, Color: (025) Castlerock / Castlerock / Anthracite
Love these little socks. Soft and stay in place, no falling down in my shoe. I will definitely be buying more. Holding up well after multiple washings.

Great fit, no slip
Size: Medium, Color: (025) Castlerock / Castlerock / Anthracite
These looked too small for my feet, but now I love wearing them as they are comfortable and stay on my feet! They look great and the colors are easy to match. Excellent value for the money in my humble opinion.
