Most Important Information

  • STRONGER: LAMBERTZ-NICHOLSON ACHILLES TENDON PROTECTOR 4.0. The Achilles tendon lies in the opening of the cushion and is thus protected from pressure and friction.

  • AIR-CONDITIONING CHANNEL® 4.0. Air-conducting 3D structures and high-tech special yarn promote intensive ventilation of the feet.

  • SUPPRONATION® BANDAGE. Supports a healthy foot posture and counteracts overloading of the ankle joint.

  • INSTEP PROTECTOR WITH AirVent Zone. 3D knitted technology prevents full-surface contact, disposes of warm, damp air, and prevents the formation of blisters.

  • AIRFLOW ANKLE PADS. A sickle-shaped arrangement of the AirFlow ankle pads gives the ankle the greatest possible protection during sports.

  • 100% PURE SWISS ENGINEERED. Made in Italy. 700+ international awards and test wins, 800+ patent registrations for the products with the "X".


Set yourself apart from the big field and secure a top spot in medium- and long-distance races with the X-SOCKS® RUN SPEED PRO 4.0 MEN. The new models of the X-BIONIC 4.0 generation will convince you that outstanding quality can be further improved.

You’ll enjoy the comfort that comes from the perfect combination of protection and ventilation functions. The finely woven fabric of these men’s socks incorporates the optimized Air-Conditioning Channel® 4.0, which ensures even more effective ventilation for the soles of the feet.

The comprehensive cushioning system, which protects against blisters and injuries caused by pressure or impact, includes the shape-optimized Lambertz-Nicholson Achilles Tendon Protector 4.0. The Instep Protector has been augmented with extended Air Cool Stripes to ward off mechanical impacts and improve ventilation in the instep area. The powerful AirFlow Ankle Pads 4.0 additionally shield the sensitive ankle zone.
