Product Description

Energize Your Legs, Energize Your Game. Only graduated compression socks:

  • are proven to increase circulation
  • improve
 speed and endurance
  • slash your recovery time

VO2fx™ graduated compression is
 measured and graduated, providing more compression at the ankle and less at the knee 
to stimulate return blood flow and reduce muscle fatigue.

Customized Padding
ProTech has custom padding knitted in the outside of the calf and outside the ankle where you need it the most. The only sock in its category with custom padding.

Perform Better
VO2fx™ is made with SMOOTHTOE® graduated compression technology. As a result, you get all the medical benefits of graduated compression in the ultimate high performance athletic sock.

The graduated compression system in VO2fx™ increases the circulation to the muscles in your legs and feet. Because of the increased circulation your legs feel energized within minutes. It supplies fresh oxygenated blood to your muscles, joints and tendons. Meanwhile, lactic acid and other fluids are transported out of muscle tissue and into the bloodstream, which dramatically reduces muscle soreness and painful swelling.

  • No bulky feeling inside the shoe
  • Mid-foot arch support means your feet feel great
