The Thorn Patch uses combined technology and creativity to produce a performance sock that offers function and style in equal measure. Our proprietary Fusion Acrylic Blend provides thermo regulation, soft hand feel, and extraordinary warmth to weight ratio, while engineered arch support eliminates foot fatigue. A fully wrapped terry loop toe box keeps toes toasty, while Y-Gore seams are knitted into the heel cup to provide feet with the perfect fitting sock. Anatomical cushion design has air channels to keep feet cool and comfortable, and every pair sports reinforced heels and toes for extra durability.
