The X-Bionic Bike Energizer is a specialised compression sock for cyclists & tour-cyclists Kompression Bike Energizer apply X-Bionics Kompression technology that combines traditional compression design in its smart compression zone along with a cooling feature that reduces fatigue & energy drain by stabilising the leg & feet muscles, while cooling them constantly. Comfort Fabrics Bike Energizer socks are made with Air Go Tex yarn, which is tremendously flexible yet comfortable due to high percentage of cotton in it. Last but not the least is the use of Robur, an impact-absorbing fibre that reduces pressure sores & blisters. Last but not the least is Skin Nodor, a yarn with polymide fiber core & 99.9% pure silver on the outside. As the body heats up, it reacts with the silver to release silver ions, completely harmless to humans but fatal to harmful bacteria, keeping the skin perfectly healthy, even if it is worn for hours. The sock also comes equipped with the convenient self-adjusting cuffs & Stretching rib for perfect fit. Air Conditioning The Air Conditioning Channel is a thinly knit mesh of fabric that runs along the side of the feet through under the arch. With every step, sweat is pushed out of the inner layer & fresh air is let in inside. The Traverse Airflow Channel system circulates air under the feet & the Airflow Ankle Pads ensure the same around the ankle joint.
