ESP

Smart protection where you need it most
Technical reinforcement developed with SEPOD for cushioning, durability and comfort

The ESP (Ergonomic Structure Protection) structure is an exclusive Lurbel system that adds extra reinforcement in the areas of the sock subject to the greatest impact and wear: toe, heel and midsole.

Developed in collaboration with the Spanish Society of Sports Podiatry (SEPOD), this system incorporates a third extra layer on the outermost part of the sock, designed to provide greater cushioning, resistance and protection without compromising adaptability or lightness.

BMAX
POLIAMIDA
ANTIODOUR BASE LAYER
Bmax fabric, in any of its versions, is knitted in loops that form small springs on which the foot rests, providing a cushioning effect and greater comfort with every step.
This additional polyamide yarn provides greater durability.
This layer exerts its anti-odour power across the whole garment as a guarantee of durability and comfort.

ESP structure
More protection, cushioning and comfort

Socks with the Ergonomic Structure Protection (ESP) system, developed with the Spanish Society of Sports Podiatry (SEPOD), incorporate a third additional layer on their outermost part. This layer works on three levels:

Greater durability

The external reinforcement adds density in the areas exposed to continuous friction, increasing the sock’s lifespan and its resistance to wear.

This additional layer offers between 25% and 40% more cushioning than a conventional sock, softening the impact of every step.

When combined with Bmax technology, ESP enhances skin protection, reducing the risk of chafing, blisters and overheating in the most sensitive areas.

ESP1
Light cushioning ESP with density level 1 is designed for repetitive impact situations with light, flexible footwear. It provides comfort without overloading the stride. Ideal for running, short trail or indoor training.
ESP2
Medium cushioning ESP with density level 2 is designed for long walks, hiking routes or use with semi-rigid footwear (such as low boots or approach shoes). It offers a balance between comfort and responsiveness.
ESP3
Maximum cushioning and protection Developed for extreme environments or very rigid footwear (expedition, ski or high-mountain boots). It provides an extra barrier between the foot and external impact.

Your stride, precisely protected

The ESP system is strategically integrated into each sock, adapting to the natural movement of the foot. The result is a garment that is more durable, more comfortable and more efficient, designed for those who never take a step without purpose.
