Designed to be ‘power socks’ for male and female runners, X-Socks Run Energiser Compression Socks access reserve energy, improve regeneration and reduce tie risk of thrombosis. X-Socks Run Energiser Compression Socks are longer, calf-high socks that use Smart Compression Zones to accelerate the flow of blood back to the heart (venous return) and generally improve blood circulation, promoting the supply of nutrients, relieving strain on the cardiovascular system and lowering the pulse rate. The ’13-way’ protection system defends and cushions, from top to toe, with self-adjusting cuffs, an air-cooling and ventilation system with air conditioning channels, anatomical right/left footbeds and padding to the ankle, toe, heel and special Lambertz-Nicholson Achilles Tendon Protectors. The socks actively pump moist air out with every step, and suck in fresh air to encourage dry, healthy feet.
