Pro 踝襪：黑色

Wore these for a week of tennis and the mesh ventilation actually keeps my feet from overheating, which I didn't expect from a sock this thin. The nylon-spandex blend hugs without squeezing, and they've stayed put through every sprint.

The mesh ventilation actually works—my feet stayed dry through a full gym session and the cushioned sole is firm where I need it. The nylon blend holds its shape wash after wash, so they still hug my arch like day one.

Took these out for a long walk and the mesh ventilation actually kept my feet from feeling clammy, which nylon socks usually don't manage. The cushioning under the foot is just right—firm enough for support, but not bulky inside my sneakers.
