Just like all Swiftwick products no issues with hot feet. They compress well and don't slid at all. Super comfortable and breathable material. I really like the colors and pattern shapes the Fiesta socks makes it easy for others to spot you.
The black ones look good. Wife loves them. Excellent quality - no issues.
I am starting to like Swiftwick more and more. Have always been a Smartwool fan for cold weather and a PI guy for warm. I like the five-inch cuff as a compromise. Too tall six-and-seven inch look stupid as do too short. These fit nicely in the middle. Well made, seamless and supportive. Good sock.
