Compressport Full Socks v2.1 Maximum grip is guaranteed due to the 3D.Dots acupuncture technology. You won`t slip during effort and blood circulation is stimulated. Those same 3D.Dots help absorb shocks and dampen impact; the Achilles tendon is cushioned and protected. One UP of these socks is their ergonomic toe piece that fits each foot; your toes are neither smothered nor compressed during effort. Its seamless and elastic-less upper layer does not pressurise your leg - As a blood-flow stimulator, the Full Socks become your ideal travel socks for the feet. A unique feature in this improved version is the one-layer hem that replaces the initial double-thick one. Less pressure and discomfort is exercised on the knee.
