Comodísimas desde el primer momento!! Llevo varios días seguidos usándolas e intentando pisar hierba por cada parque que paso, je, je! El tono claro combina con todo. Muy contenta con la compra.
These are the reference measurements.
It is important not to focus on the numerical size of the conventional footwear you usually wear (e.g., size 38), but rather on the number of cm your feet measure (24.2cm). Below, we explain how to measure your feet correctly.

It is important not to focus on the numerical size of the conventional footwear you usually wear (e.g., size 38), but rather on the number of cm your feet measure (24.2cm). Below, we explain how to measure your feet correctly.
The footwear must NOT fit tightly; an appropriate amount of space must be ensured so that your foot can expand and contract freely. In this case, we recommend leaving between 0.7cm and 1cm of space for narrow/regular feet, and up to 1.3cm for wide feet or those seeking a roomier feel.
This is the size guide for this model. The length corresponds to the length of the inner insole. Remember to select the size that ensures an appropriate amount of space for your feet.

A conductive barefoot shoe that preserves the foot’s natural freedom and maintains electrical contact with the ground.
ROOTS’ exclusive KARV™ upper tech integrates a high-performance structured fabric with a multicomponent construction. Made from highly durable synthetic fibers combined with cotton and elastane, it offers the perfect balance of lightness, durability, adaptability, and resistance to intensive use. In addition, the upper is reinforced with heat-sealed TPU to provide support without adding stiffness or unnecessary seams.
Integrated system of conductive fibers, threads, and fabrics running through the inside of the shoe from the insole to the sole. Each layer is designed to maintain electrical continuity and prevent interruptions within the footwear structure.
The final interface with the ground. The sole incorporates areas of technical rubber formulated with conductive carbon particles, creating contact points that complete the conductive path from the foot to the ground.
Overall rating: 5.0 / 5 from 4 reviews.

Barefoot sole made of technical rubber, 4 mm and zero drop, designed to maintain flexibility, grip, and ground sensitivity.
It incorporates Ground Contact Carbon™ technology in the forefoot and heel: rubber zones with conductive carbon connected by the Multilayer Conductive Architecture™.
A thin, non-slip, and durable construction that completes the conductive pathway from the foot to the ground.
Durante las últimas dos décadas, el grounding ha sido objeto de numerosos estudios científicos que han investigado cómo el contacto eléctrico con la Tierra puede influir en distintos procesos fisiológicos del organismo. La evidencia publicada hasta la fecha ha mostrado resultados prometedores en áreas relacionadas con la inflamación, el dolor, la recuperación física, el estrés y la calidad del sueño.

It’s not a simple concept, and you deserve to have all the information at your disposal. Here you’ll find studies, comparisons, and other helpful materials.
