Trust the technologically perfected X-SOCKS® MARATHON HELIX RETINA 4.0 and get ready for the challenges of long runs.
These special Generation 4.0 socks are designed for endurance runners and made with ultra-high definition Retina® technology. The integrated HelixCoil system supports the muscles of the calves and reduces the risk of fatigue-related injuries. 
The knitted fabric, which precisely embeds the optimized Air-Conditioning Channel® 4.0, also enables highly efficient ventilation. To protect against pressure, impact and friction, the shape-optimized Lambertz-Nicholson Achilles Tendon Protector 4.0 with its two-part padding encloses the sensitive zone above the heel. Together with the heel protector, the AirFlow Ankle Pads further reinforce the protective space around the heel and ankle.
