Having just received them, I cannot but speak to initial impression, but I will say they begin wonderfully. They are soft and filling, the first pair of socks I have purchased in a very long time that don't feel like they've robbed my of an inch or three at the top, yet not so high as to be kneesocks... not very manly that..

Time will tell on the construction, but initial comfort is something that takes highest marks. They are of a medium weight, surely a Goldilocks range, likely well suited for all seasons of wear, but for extremes of winter or summer.

On size, I would note they run a bit big, again counter to most other companies whose socks almost always run very small to adverts. I purchased the large and wear a size 11.5 to 12 shoe, and would say they are a smidge large on my feet, but nothing I am not comfortable with. I am not swimming in them, but only just not. I would suggest they would most perfectly fit a foot ranged from 12-13 shoe size.

The true test will be in durability, for I have yet to find a pair of socks which makes it even a year of normal use without sprouting holes under the heels. I believe they are guaranteed for a year of normal use, so I've got that going for me.

All in all, they meet or exceed my expectations. They are not cheap in price, and they seem not cheap in material. I'll take that deal.
