Get the momentum you need for challenges on demanding terrain with the X-SOCKS® COMBAT SILVER 4.0. The highest material quality distinguishes these socks from the X-SOCKS® 4.0 generation. The Apani® Merino Wool and Apani® Silk, both with high thermoregulatory quality, are proven comfort features, as is the disinfecting and odour-reducing Sinofit footbed. Thanks to consistent innovation, these special socks deliver even more technological precision. The completely redesigned Air-Conditioning Channel® 4.0 with its reshaped, upwardly narrowing air channel ventilates the sole of the foot even more effectively. And the Lambertz-Nicholson Achilles Tendon Protector 4.0 with its two-part shape provides even better protection for the sensitive zone above the heel. Night Touch on the left sock helps to distinguish the socks by touch when putting them on in the dark.
