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 is the perfect choice for young ski beginners and sporty, ambitious ski kids. Shock-absorbing zones protect toes, feet, and calves all around—no chafing, no pressure points. Integrated technologies wick away moisture, keep the foot dry, and regulate temperature. A stretch component in the material ensures a cozy, comfortable fit. The new Suppronation® footbed supports a healthy foot position, reduces the risk of overexertion, and increases endurance during intense winter sports.
