BootDoc Race Merino PFI 50 Sock Black, S

What Our Gearhead(R) Experts Are Saying:"I like these when I want a really thin sock that keeps my boots feeling precise. The merino keeps things comfortable, and the light compression adds just enough support without feeling bulky."When every millimeter of fit matters, a thinner sock can make all the difference. The Race Merino PFI 50 Sock is designed for skiers who want precise boot feel with lightweight warmth and subtle support. Its slim racing construction minimizes bulk inside performance ski boots, helping maintain a close connection between foot and boot. Light compression rated at 10-15 mmHg promotes circulation and helps maintain a secure, stable fit during active days on snow. A high percentage of merino wool provides natural temperature regulation and moisture management, keeping feet comfortable across a wide range of conditions. Integrated copper threads add anti-odor properties, helping maintain freshness through long days on the mountain. Reinforced toe and heel zones increase durability in high-wear areas while maintaining the sock's lightweight feel. The result is a streamlined ski sock that balances precision, warmth, and everyday comfort for demanding days in ski boots.
