Give new impetus to your enthusiasm for running and get on your way toward a new level of performance with the X-SOCKS® RUN PERFORMANCE 4.0 MEN. The patented high-tech functions of the X-BIONIC® 4.0 generation create ideal feel-good conditions so you can achieve your best performance on every course.

You benefit in three ways from the perfect fit for men’s feet: you enjoy more protection thanks to the intelligent padded zones in the optimized Lambertz-Nicholson Achilles Tendon Protector 4.0 and the improved AirFlow Ankle Pads 2.0; you gain endurance thanks to the ventilated Air-Conditioning Channel® 4.0 and the climate regulating Instep protector with AirVent Zone on the back of your foot; and you’ll experience more comfort with stabilizing features like the Pull-On Non-Slip Flap® at the heel, which prevents the sock from slipping into the shoe.

Albedo® 360-degree reflective yarn on the outer hem increases safety in the dark.
