Under Armour's Ignite footwear has always brought top performance to your feet. But now, it's also backed up by your socks. The Ignite Crew Socks use UA's Signature Moisture Transport technology to pull sweat from the skin and accelerates its evaporation. Then ArmourBlock® goes to work, preventing this moisture from causing bacteria or odor growth. Underneath the foot, an Embedded Arch Support helps reduce foot fatigue. 72% polyester/25% cotton/3% spandex. Imported.
