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