The X-Bionic Marathon Retina 4.0 socks are designed for use in long distance running. The Special Generation 4.0 socks for endurance runners are made with ultra-high resolution Retina technology. The knitted fabric, which accurately incorporates the optimised Air-Conditioning Channel 4.0, promotes very effective ventilation. The Lambertz-Nicholson Achilles tendon protector 4.0, in an optimised way, with its two-piece cushion, encloses the sensitive area above the heel to protect it against pressure, impact and friction. Together with the heel protector, the AirFlow ankle pads also reinforce the protective space around the heel and ankle.

They incorporate Helixcoil technology, which offers optimal muscle support.

- Anatomical footbed

- 9% elastane
- 69% polyamide
- 22% polypropylene

- Helixcoil System
Two concentric and spiral pressure fabrics integrated into the sock structure that encloses the calf muscles from ankle to knee. An effective muscle support without affecting blood circulation.

- Lambertz
-Nicholson Achilles Tendon Protector
Thanks to the use of a material highly resistant to abrasion and shock absorption, this protector protects the Achilles tendons from pressure points and friction in the upper part of the shoe. In this way, the tendons are not under stress because they are located in a cushioning capsule.

- Air Conditioning Channel
Consists of a ventilation system made up of channels that flow around the body, continually transporting heat and moisture. This system enables air to flow to parts of the body that are not usually accessible to fresh air circulation.- Traverse AirFlow Channel System
Regulates the temperature of the sole of the foot and directs moist and warmed air to the ventilation channels.

- Retina
Retina provides optimised function signalling and efficiency for better cooling and support. As with the millions of sensors in the human retina, more information from the skin can be processed. Which leads to unprecedented results.
