Loved this product!
Number of Items: 6, Color: Black/Graphite (6-pairs), Size: Large
I wear a size 8.5 or 9 in men shoes and this socks fit perfectly for me. They have the right amount of cushioning and support that I was looking for. Not too much that makes wearing shoes uncomfortable and not too little that feels like I’m not wearing anything. Will buy another set

Heels wear out fast.
Number of Items: 6, Color: Black/Graphite (6-pairs), Size: Large
The heels wear out quickly. Disappointing. I’m retired and don’t put undue stress on my clothes. I wouldn’t buy them again.

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.
