80% Cotton, 17% Polyamide, 3% Elastane CERTIFIED SAFETY – The grip dots that we use to produce our socks are the BEST existing SAFETY SYSTEM for your feet on the market. The Italian silicone ABS located on the bottom of the sock has received Oeko Tex Standard 100, GOTS (Global Organic Textile Standard). In order to receive such an important certificate, the material went through numerous tests which confirmed the top quality and safety of our socks, unlike the hardening low-quality rubber grip dots from Asia. WIDE APPLICATION – Non-slip Rainbow Socks are ideal both during yoga, Pilates, or fitness classes and during dance classes, martial arts, and other types of exercises. Owing to their grip, you won’t risk slipping on the floor and losing balance during exercises. They’re also extremely comfortable for walking around the house. Owing to the cotton fabric with nets, the socks are breathable and guarantee no compression. IDEAL FOR TRAMPOLINES – Non-slip Rainbow Socks are used by several dozen trampoline parks in Europe! Owing to high quality, our socks have been appreciated and ordered in bulk quantities by professional entertainment parks. That’s why our Non-slip Rainbow Socks are also ideal for home use on trampolines in our gardens. In Rainbow Socks, our feet will feel comfortable, won’t slip, and won’t perspire so much. HIGHEST-QUALITY EUROPEAN PRODUCT – In order for our socks to stand out on the market filled with cheap (and often hazardous) Chinese products, we produce them in the EU in a small family company which has been dealing with sock production for three generations. Product quality is treated as a point of honor, which is visible in many positive reviews all over the world! The quality of the produced socks has also been appreciated and confirmed by the international OEKO-TEX certificate.
