Sock Geek Says:

Slightly more compression than the "Original" Oxysox and without the underfoot cushioning. If you prefer a little more support and a thinner, second skin type of feel then the Oxysox Flat Knit is the way to go.

Patented graduated compression sock that helps to improve circulation and reduce muscle fatigue resulting in better performance.  Testing has indicated the following benefits of wearing OxySox:

• Reduced leg fatigue/pain post exercise
• Better stability for injury prone areas
• Faster blood return to the heart and lungs
• Can improve the return of oxygenated blood to the legs
• Can improve energy levels and endurance
• Increased calf muscle pump efficiency
• Elevated aerobic capacity (VO2 max)

Oxysox have a double-welt top for a comfortable non-slip fit.  Arch and foot compression for support and reduced blistering.  Breathable mesh instep. Infused Alphasan® antimicrobials control bacteria and odor for a fresher feeling.  Lightweight and breathable polypropylene equals superior moisture management.

"Sock Geek" Steve has been wearing the Oxysox during some of his longer training runs and during his last two road marathons and feels that they enhanced his performance and reduced post run soreness.
