Lurbel Bmax Challenge Four Socks

The Desafío Four socks come with a new design and height H4 (8cm above the shoe).

Seamless socks, reinforced in areas of high friction, provide greater comfort and durability for trail running.

They are made with BMAX technology , which helps combat overheating, moisture, and friction, which cause blisters, keeping your feet in perfect condition.

In addition, reinforcements are added to the areas of the sock most exposed to wear and tear, along with 25% to 40% more cushioning.

Ergonomic ESP protection structure developed in conjunction with the Spanish Association of Sports Podiatry, reinforcing the points of greatest friction.

Made with Silver Base Layer technology , a silver ionized thread structure that has great antibacterial power to eliminate bad odors produced by bacteria.

It incorporates the new A+ system for greater support and durability. This is achieved with a double rubber cuff that prevents the sock from slipping and stays in place, thus preventing sand or pebbles from entering.

Recommended especially for medium distances or short ultras.
