Good value compared to alternative brands.
These are as good, if not better than smart-wool crew height socks. Some may object to their lower merino wool percentage, but if you live in American southeastern muggy weather, you will appreciate the higher nylon content. Can wear them in both extremely hot humid 90+ degree weather, as well as 32- freezing weather.
Good overall
These socks are comfortable and I believe good quality but have more cushion than I would expect from lightweight socks
Not 100% merino, Not Large, and Not blue
I thought I had ordered 2 pairs of 100% merino socks in a men's size Large, color blue. What I received was 2 pairs of socks that were 40% merino womans size medium socks that were gray/black/yellow. I'm donating them to the local thriftshop, so at least someone else will benefit from my loss.
Not one part was a described
Supposed to be men's large, wool, and blue. None ended up as described: wm's med, 40% wool, and gray/black/yellow. I can't wear them, so I'm donating them to charity.
