More skiing fun and safety for children. Innovations from 20 years of experience offer a high level of safety and comprehensive comfort for little feet. X-Socks 4.0 Ski Junior 4.0 are the perfect choice for young ski beginners and sporty, ambitious ski kids. Shock-absorbing zones provide all-round protection for toes, feet and calves - no rubbing, no pressure points. Integrated technologies wick away moisture, keep the foot dry and regulate the temperature. A stretch component in the material guarantees a cosy, comfortable fit. The new Suppronation footbed supports a healthy foot posture, reduces the risk of overloading and increases endurance during intensive winter sports.
