YOUR SECRET TO SUCCESS: ALWAYS BE A STEP AHEAD. Stay relaxed but on business still in top form: X-SOCKS® Liberty allows the freedom to do both at the same time. Every day. That’s taken care of by an intelligent mix of matierals that includes cotton, Lyrca and Elastane. On the toes and heels they offer effective protection against friction and stubs. Under the anatomically formed footbed the patented X-SOCKS® Air Condition Konzept works uninterrupted for your well-being: Finely designed channels direct moist, warm air away from the foot and carry fresh air back in. The patented X-SOCKS® Technology AirConditioning Channel®, Traverse AirFlow Channel System™, AirCool Stripes and AirGuides™ utilize the pump effect of the arch of your foot. The Instep Protector cushions the foot’s metatarsals and reduces chafing.
