Under Armour Ignite Crew Socks - Men'sUnder Armour's Ignite footwear has always brought top performance to your feet. But now, it's also backed up by your socks.

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.
