What Our Gearhead® Experts Are Saying:"I like these for colder, more aggressive ski days when I want a really dialed fit in my boots. The strong compression keeps everything feeling locked in, and the merino blend adds warmth without bulk."When ski days get longer, colder, and faster, your gear needs to keep up. The Performance PFI 90 Sock is designed to deliver maximum support, warmth, and precision fit inside high-performance ski boots. Built with strong compression rated at 20–25 mmHg, the sock promotes circulation while helping reduce fatigue during demanding days on the mountain.
