These skis are great fun. Designed to fit any foot up to size 9 (42) shoe size, the adjustable ski straps wrap around the back of the boot and pulled tight over the front top of the foot using the self locking buckles provided. The mini skis are very popular in Scandanavia. Using balance and co-ordination, carving skills and stopping they make very good disciplines when learning how to ski without poles. Hours of fun!!!
