X-Socks Run Speed Two 4.0 Calzini Uomo, grigio

Always stay one step ahead and benefit from the performance boost of innovative technologies with the X-SOCKS 4.0 RUN SPEED TWO MEN. With their optimally combined ventilating and protective functions, these X-BIONIC 4.0-generation socks are perfectly suited for medium- and long-distance races. Compared to previous models, you can expect even more comfort and performance-enhancing precision.

The newly designed Air-Conditioning Channel 4.0 is embedded in the densely knit material to ventilate the soles of the feet. The Instep Protector with extended Air Cool Stripes provides air conditioning for the back of the foot and simultaneously protects the instep against pressure and friction, while the SUPPRONATION-BANDAGE over the anke inhibits over-pronation or -supination and stabilzes the foot in its natural rolling movement.

The comprehensive cushioning system also includes the high-performance AirFlow Ankle Pads 4.0 at the ankle, the shape-optimized Lambertz-Nicholson Achilles Tendon Protector 4.0 above the heel.

Skin Nodor
Skin Nodor is a climate-active nano-filament and reduces bacterial growth and perspiration odour. An inorganic bacteriostatic active ingredient 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.

Air Guides
As spacers to the shoe, they support the continuous exchange of air along the AirConditioning Channel and protect against blisters. Because the drier the skin, the lower the risk.

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.

Extensor protector
The three-part protector keeps the tendon, which runs in two strands, pressure-free.

AirVent Zone
The 3D knit technology provides effective ventilation.

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
When exercising at dusk or at night, light is reflected. No matter which direction it comes from.
