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.

  • SMART COMPRESSION ZONE. Improves blood circulation, reduces muscle vibration.

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


Activate your full strength on any run with X-SOCKS® RUN ENERGIZER® 4.0 MEN. The over calf model from the X-BIONIC® 4.0 generation delivers unmatched perfection from X-SOCKS® innovative labs. Precisely positioned functional zones provide even more comfort than you previously enjoyed with X-BIONIC® products. Among the perfected technologies is the Air-Conditioning Channel® 4.0 with a fresh air-pump effect to optimally ventilate your sole. To enhance the relaxed barefoot feeling, the Lambertz-Nicholson Achilles Tendon Protector 4.0 with its reinforced, shape-optimized padded zones absorbs the pressure and friction of the shoe and cushions the impact of running on uneven terrain. The strength of the X-SOCKS® Run Energizer® 4.0 also lies in the activating effect of the Smart Compression Zone: gradual compression accelerates the transport of venous blood to the heart. Your cardiovascular system is relieved and you have more energy available for long-lasting performance.
