Growing feet love fresh air, which is why Oppsal Mid GTX is designed to give your child's toes some room to breathe. This reinvigorated, adaptation of one of Viking's best-selling models is now part of Vikings Sustainable choice collection. The rubber outsole is made of a recycled rubber mix. It has approximately 30% recycled PU on toecap/reinforcement and 100% recycled polyester laces. It also features smart reflective details and offers an extra airy toe box that allows toes to spread naturally and comfortably. A waterproof and highly breathable GORE-TEX membrane also ensuring foot comfort in all types of weather. Finally, a supportive yet lightweight textile mid-cut upper along with an ultra-light EVA midsole will add serious airtime to your little junior's jump!
