These are the 9th pair of these socks I've gotten for my husband. he loves them - they stay up and keep his feet cool. he wears a size 10 (cole haan) and the 8-10 size fit him well.
They are socks. They are a wool blend. But, they didn't fit all that great on my size 13. I'm 6'2" and they landed mid calf. They didn't stay up all day for me, but I have "Athletic" calves that can be picky. I won't be purchasing them again.
All that said, they did fit their purpose for me and will be in my "emergency" sock pile.
Buying these socks from Nordstrom has become an annual event. They fit my husbands size 14 feet unlike most other stores mens XL sizes. He likes the wool blends feel and since his dress at work requires mens dress shoes, we have buy 6+ pairs of 2 colors during the annual sale for the past 10+ years. Difficult to find such high quality big and tall staples -- Thanks Nordstrom!
