The special generation 4.0 socks for endurance runners are manufactured in ultra-high resolution Retina® technology.

The knit fabric, which precisely embeds the optimized Air-Conditioning Channel® 4.0, promotes highly efficient ventilation. The shape-optimized Lambertz-Nicholson Achilles Tendon Protector 4.0 with its two-part cushion encloses the sensitive zone above the heel to protect against pressure, impact and friction. Together with the Heel Protector, the AirFlow Ankle Pads additionally reinforce the protective space around the heel and ankle.
