Nice socks.
Comfortable socks: who could ask for anything more? They seem to be of a nice quality, but I buy socks often so there's a rotation going on. A little pricey, but ankle socks always have that sporty look. Fit well, but kind of thin, which isn't a deal breaker.

Best socks on the market
Number of Items: 6, Color: Black/Graphite (6-pairs), Size: Medium
I highly recommend purchasing multiple orders of these socks. I used to wear puma socks that had the padding around the arch and were extremely thick (being that my feet are always cold) i wanted something thick again especially during the winter time. I have had these socks for over two months and I can truly say that they were a better purchase than my pumas. They are so thick that wearing even one pair will still fit into my tennis shoes or running shoes but my toes NEVER get cold. I put a lot of wear and tear on them and they have never started tearing on the bottoms like most socks do. Socks usually develop holes or tears from the friction but I wore the same pair over and over again while walking 13+ miles a day and I cannot tell any sign that these are going out on the bottom. I highly recommend purchasing multiple pairs of these socks.

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...
