Compressport ProRacing Full Socks Ultralight Eight 3D-dots that acupressure on eight micro areas of your feet, will stimulate blood circulation. The 3D.Dots protect the Achilles tendon and the malleolus area. Shocks are easily absorbed, limiting muscle pulling. Maximum grip is guaranteed due to the 3D.Dots acupunctured-technology. You won`t slip during effort and blood circulation is stimulated. The socks being positioned around the arch of the foot, compression stimulates venous return, strengthens stride posture and limits curvatures. The toe piece fits ergonomically; your toes are neither smothered nor compressed during effort - Its seamless and elastic-less upper layer does not pressurise your leg.
