Sock Guy Pirate Socks
Sock Guy Pirate socks are made with 75% ultra-wicking Micro Denier Acrylic, 15% nylon, and 10% spandex for exceptional comfort and strength. Sock Guy socks feature "Stretch-to-Fit" sizing and an exclusive "Easy-fit" cuff for a perfect fit every time on any foot. These features create superior softness and comfort and help eliminate blisters and hot spots. Also featuring a double stitched heel & toe for added strength and durability.
The cuffs are great, the breathability is really good, and the durability is fantastic: I've worn mine for over 4 years and they are still going strong. I now own more than a couple pairs.
Bought more than one pair, they are very good bike socks: good strong cuffs that don't slip down, well-fitting and breathes well too, with a sturdiness that takes on anything you throw at it.
