X-Socks Marathon Energy 4.0 Calzini Uomo, nero/grigio

X-SOCKS MARATHON ENERGY 4.0 MEN give you a performance edge in long-distance running. With even more patented technologies, the newly designed X-BIONIC 4.0 product generation provides the decisive impetus for outstanding performance. Innovative technologies optimally equip your feet for the specific stresses of a marathon.

The Air-Conditioning Channel 4.0 directs fresh air to the sole of the foot and ensures a pleasant, comfortable climate. In contrast to its predecessor, the channel integrated into the fabric is narrower in the upper area and increases air permeability. The Air Guide technology and the Traverse AirFlow Channel System provide additional ventilation.

In the perfected version of the X-BIONIC 4.0 generation, the Lambertz-Nicholson Achilles tendon protector 4.0 protects even more effectively against pressure, friction and impact with its shape-optimised padding structures. The Suppronation Bandage also keeps the feet of long-distance runners stable and ready for fatigue-free performance.

Skin Nodor
Skin Nodor is a climate-active nano-filament and reduces bacterial growth and perspiration odour. An inorganic bacteriostatic agent is incorporated into its interior. Skin Nodor only develops its effect through the slow release of ions, activated by body heat. The ions prevent the proliferation of microorganisms, while at the same time protecting the skin's sensitive ecosystem and preventing allergic reactions. Skin Nodor is particularly soft and breathable and ensures an excellent fit.

Mythlan
Skin-neutral and anti-allergic lightweight fibre reduces the build-up of germs and bacteria.

Bisentio
This multifunctional hollow fibre is breathable, elastic and offers excellent properties. It absorbs pressure and shocks thanks to the air contained in the fibre core. The high-quality three-thread construction is extremely durable and abrasion-resistant.

Active waistband
Secure hold without slipping and constriction, adapts to any leg circumference.

Air-Conditioning Channel
The Air-Conditioning Channel made of fine mesh knit is an air conduction system that continuously ventilates and air conditions the foot and leg. It leads out of the anatomically moulded footbed on the inside of the foot, ensuring that moist and overheated air is pumped out of a tight-fitting shoe with every movement of the foot.

Lambertz-Nicholson Achilles tendon protector
With its highly abrasion-resistant and shock-absorbing material, it protects the Achilles tendon from pressure points and friction caused by the edge of the shoe. The sensitive Achilles tendon is not strained as it is embedded in the opening of the pad.

Stretch rib
Ensures elasticity and a perfect fit.

Suppronation bandage
Supports a healthy foot posture and prevents overloading of the ankle joint.

AirFlow ankle protection
The ankle protrudes from the side of the leg and is often scraped in the event of a fall. The crescent-shaped arrangement of the pad offers the ankle the greatest possible protection without affecting the exchange of air via the Air-Conditioning Channel.

Traverse AirFlow Channel System
The 3-channel cross ventilation system helps to absorb moisture and heat into the air conditioning channel. It also air conditions large areas of the sole of the foot that is normally firmly enclosed by the shoe.

Toe protector
Cushions pressure and adapts perfectly to the asymmetrical toes. Protects them from blisters and chafing.

Toe tip protector
The asymmetric protector made from shock-absorbing Robur hollow chamber yarn cushions and protects the pressure-sensitive tip of the toes.

Instep protector with AirVent Zone
Increases the shock-absorbing effect of socks and allows air to circulate through channels.

Heel protector
The heel protector protects against pressure and friction.

Albedo 360° Reflective Technology
Light is reflected when doing sport at dusk or at night. No matter which direction it comes from.

CentralFlow AirCool Stripes
Fresh air is distributed under the entire sole of the foot.

Anatomically moulded footbed
For the "L"-left and "R"-right foot with integrated Air-Conditioning Channel.
