Active High PFI 70 Sock

What Our Gearhead® Experts Are Saying:

"I like using compression ski socks like these on long days because they help reduce fatigue and keep my feet feeling supported inside tight boots. The reinforced areas hold up well when you're putting in full days on the mountain."

A long day on the mountain starts with comfortable feet. The Active High PFI 70 Sock combines targeted compression and durable construction to help keep skiers and riders comfortable from the first lift to the last run.

Designed with medium compression (15–20 mmHg), the sock supports circulation and helps reduce fatigue during extended time in ski or snowboard boots. Arch-specific support helps stabilize the foot inside the boot, improving comfort and control throughout the day.

Reinforced zones at the toe and heel increase durability in high-wear areas, while integrated Achilles protection adds cushioning where boots often create pressure. Knee-high coverage provides consistent compression and protection along the lower leg.

CuTEC technology incorporates copper fibers designed to help manage odor and maintain freshness during active use. The performance fabric blend balances stretch, durability, and moisture management to keep feet comfortable through changing conditions.

Whether carving groomers, riding powder, or logging long resort days, the Active High PFI 70 Sock provides supportive comfort built for time spent in ski and snowboard boots.
