The X10D sock is a functional sports sock developed by Tobias Schumacher, featuring unique 3-Vector technology. The idea for this functional sock concept arose from the drive to develop a sports sock that optimizes gait—with a biomechanical focus to support the natural function of the foot during sports. The development and technology originate from Switzerland (Swiss Development), while production takes place in Italy (Made in Italy). At the heart of the X10D sock is the patent-pending 3-Vector technology.

The 3-vector technology is the central feature of every X10D sock. On the so-called vector board, three vector triggers positioned specifically on the sole contact area act on the wearer's gait. In combination with the sock, the 3-vector technology can lead to a physiologically more natural and upright gait. The X10D socks also improve the foot's natural cushioning function, especially during sports with high impact forces. The X10D socks stand for the highest wearing comfort and provide a more stable running feel during sports or also in everyday life. The technology was developed in Switzerland and has been filed for a patent (as of September 2026).

X10D socks are available in two versions: 

Light – lightweight and breathable, designed for warmer conditions and fast-paced sports such as running, football, tennis, padel, golf and squash.

Robust - durable and versatile, also designed for running, trail running, hiking and summer trekking. For cross-country skiing and ice hockey in winter. 

The Robust versions provide a more noticeable compression effect.

The material composition varies depending on the model. The Light models are made of polyamide, polypropylene, polyester and elastane. The high polypropylene content is crucial for moisture management – it actively wicks moisture away from the foot. All socks are produced in Italy.

X10D socks are washable on a gentle cycle at a maximum of 40°C. Do not use fabric softener – it impairs the moisture-regulating properties of the polypropylene content. Air dry or tumble dry at a low temperature. Do not iron.

You can find the size information directly on the respective product page. X10D socks are available in common shoe sizes. If in doubt, we recommend choosing the larger size – the elastic materials adapt well.

Yes. X10D socks are available as special children's socks with the same Swiss Biomechanics 3-Vector technology as the adult models. Children's socks are available in sizes 32 to 34. Suitable for sports, school, and active everyday life.
