Description

High-compression running and trail socks, a more stable microclimate, and quick-drying and breathability

Push harder, recover better, and protect your muscles even during intense exertion with the ULTRA 1638 high-compression calf sleeve, designed to provide firm support and superior control in every sport. The targeted compression wraps around the calf with a powerful and stable effect, increasing tissue oxygenation, improving muscle endurance, and helping to reduce recovery time and the risk of microtrauma during intense workouts, climbs, sprints, and high-frequency sessions.
The elastic, anatomically designed insert enhances movement awareness and provides consistent stability, promoting a more secure footing and more efficient running mechanics. The breathable microfiber and Lycra® construction optimizes sweat evaporation and keeps the skin dry even on the hottest days or during extended sessions, helping to maintain a consistently comfortable internal microclimate.
Designed for maximum versatility, the ULTRA 1638 is ideal for running, trail running, cycling, trekking & hiking, and fitness & training, offering a supportive fit that reduces muscle vibration, supports athletic movement, and ensures a snug, non-slip feel.
Lightweight, stable, and high-performance, it’s the right choice for anyone looking for advanced compression, targeted support, and faster recovery—all in one calf sleeve.
