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.
