Lurbel Desafio Three Black Red

The Challenge Three is the low-cut version of the Challenge family: an H3 height trail running sock with a low cut (6 cm above the shoe), designed for medium distances when you want lightness around the ankle without sacrificing support. It features a new sizing system to improve the fit and achieve a more precise feel inside the shoe, especially on uneven terrain and during changes of pace.

The construction focuses on true comfort: seamless around the perimeter and with a closed toe box to reduce chafing in sensitive areas. The extra +A fit at the cuff reinforces stability without a feeling of pressure, and is combined with enhanced breathability zones in high-sweat areas to help keep the foot drier. On the instep, the adaptability strip with an anti-slip effect helps the sock stay in place and prevents it from shifting inside the shoe when the terrain gets challenging.

Its technical core is Bmax Tetra, developed to combat the main causes of blisters: overheating, moisture, and friction. The structure is designed to quickly wick away sweat and maintain a cooler foot feel during high-intensity activity, protecting the skin during exertion. Underfoot, the ESP 1 plantar structure provides functional protection in high-stress areas, and the Antiodour Base Layer, with its cross-sectional antibacterial action, enhances odor control and performance durability.

Developed, patented, and locally produced in Ontinyent (Valencia), Desafío Three is a direct commitment to the mountains: a stable fit, protected skin, and lightness with every stride.
