Built-in conductive system · Made in Spain
Shipping to mainland Spain and the Balearic Islands · 14-day returns from delivery
100% natural leather barefoot shoe, both inside and out.
Features innovative sole technology, consisting of a metal alloy that makes contact with the ground and is connected to a metal thread that touches the foot directly.
Sole made of TPU (thermoplastic polyurethane), a flexible, resistant, and durable material.
Leather-lined insole stitched with metal thread.
Minimalist design that respects the biomechanics of barefoot movement.
Exceptional comfort thanks to its artisanal construction and premium locally sourced materials.
Available in a combination of aubergine green and safari green colors.
Conductive technology
We have developed a conductive system built into the shoe that connects your foot to the ground when you step on a conductive surface.
The insole is stitched with metallic thread that touches the foot, and that thread joins a metal-alloy arch built into the sole, with contact points in three positions to support contact with the ground whatever your stride.
ImportantThis footwear makes it easier for the body to connect electrically with the ground. Do not wear it to handle electrical installations or appliances, or for work with electrical or static-electricity hazards. It is not safety footwear, it is not insulating and it is not personal protective equipment (PPE).
