These aren't just any old socks. The Under Armour Performance Tech unisex socks are engineered for athletes and active lifestyles, delivering a powerful combination of breathability, moisture management, and all-day comfort. Made from durable, fast-drying fabric and featuring the innovative Locked-In Fit design, they stay securely in place from your first step to your last rep — no slipping, no adjusting, no distractions. Each pack contains three pairs, so you're always ready to perform.
The Locked-In Fit system is the standout technology of these socks. A specially engineered heel construction grips the foot and prevents the sock from sliding down or bunching up during movement. Once on, they stay put — whether you are sprinting on the track, working through a gym session, or spending a long day on your feet. No constant readjusting means you can stay fully focused on your performance. This is one of the most practical improvements Under Armour has built into their Performance Tech line.
Constructed from a 98% polyester and 2% elastane blend, the Performance Tech socks are built to manage moisture effectively. The fabric draws sweat away from the skin and channels it to the surface, where it evaporates rapidly. This keeps your feet dry and comfortable even during high-intensity workouts or in warm conditions. Fast drying also means these socks recover quickly between sessions, maintaining their freshness and performance wash after wash.
Medium cushioning is placed strategically across the entire footbed, from heel to toe. This level of padding absorbs impact during dynamic movements — running, jumping, and lateral cuts — without making the sock feel heavy or oversized inside your shoe. The cushioning protects the high-impact zones of the foot while maintaining a close, natural fit, so your footwear still feels responsive and precise. It strikes the ideal balance between protection and performance feel.
Open-knit mesh panels run across the top of the foot to create dedicated ventilation zones. These panels allow air to circulate freely around the foot, dissipating heat that builds up during intense activity. Coupled with the moisture-wicking properties of the base fabric, the mesh panels work together to regulate foot temperature effectively. The result is a sock that feels cool and fresh even during extended wear or in warm training environments.
A structured arch support band is woven directly into the midfoot area of each sock. This compressive zone helps stabilize the arch, distributing pressure more evenly across the foot during activity. By reducing the strain placed on the plantar fascia and surrounding muscles, the arch support plays a key role in minimizing foot fatigue — making these socks an ideal choice for athletes logging long training hours or anyone who spends extended periods standing or walking.
