Sock it to me
Number of Items: 6, Color: White/Graphite (6-pairs), Size: Medium
These socks are super comfortable. They are really soft and cozy and fit well.
However, they were advertised as "no show" socks and I even recently bought Under Armor shoes and they definitely show. I personally do not care about that in the slightest but thought I should mention it. It seems weird they advertise it that way but then it is not the case..
Anyway my only fault with the product is that these socks are THICC. Like these aren't cheap socks at all they feel luxurious but are quite thick in the shoes. I'm assuming this will be great once I start running since it should help absorb the impact, but otherwise it makes shoes feel a little tight. That's my only complaint with an otherwise high-quality product.
Update: I don't know what in the world people are doing to them but I have had and washed them multiple times for months since I bought them and they have fared fine. You could maybe wash them inside out but I don't particularly do that and they have been fine.
I separate white laundry from colors, are people being lazy and forgetting to do so? Don't blame the product...

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.
