Swiftwick FLITE XT® is the most technologically advanced cross-training sock ever developed. Engineered to improve stability during fitness activities that require quick lateral transitions, FLITE XT® incorporates our GripDry™ Fiber and AnkleLock™ Technology. GripDry™ was developed using an innovative grip fiber to prevent your foot from slipping inside your shoe, but we didn't stop there. We blended it with our signature Olefin fiber to wick moisture and keep your feet dry. Then we took it one step further. We added AnkleLock™ Technology, which offers extra support around the ankle during high-intensity training. Take FLITE, stability never felt so good.

  • GripDry™ Fiber prevents slipping inside your shoe
  • AnkleLock™ Technology provides targeted ankle support
  • Flex Channels improve range of motion and moisture control
  • Medium Cushion and Moderate Compression

54% Nylon / 24% Polyester / 19% Olefin / 3% Spandex

This overachiever is the most technologically advanced sock for all-around stability and support. The superhero FLITE XT uses AnkleLock Technology™ to support your ankles during repetitive movements, while proprietary GripDry™ Fiber is made up of tiny nanofibers that grip to your shoes to minimize movement and slipping, keeping you on track toward your goals. The medium cushion and moderate compression provides comfort during high impact movements, hugging the contours of your feet to support your arch and create a comfortable landing. Whether you are performing HIIT training at home, swinging your racquet on the court, walking 18 holes, or running a race - these socks have got you covered.
