If this Run sock was a character you were building in video game, you'd need to unlock a few levels to dial it in. The new tech foot - while not a cheat code - brings you closer to total invincibility. The cushion underfoot adds coziness, while giving rebound to your step. All the while, the high-density Merino Wool knit wraps the foot for blister-free comfort. It's not even beast mode, it just is.
