CE certified MX boot in children's sizes from Alpinestars at a really good price. The boot has a low profile for best comfort and is made from skin and plastic with carefully placed flex zones, making it flexible. The integrated sole makes the boot waterproof and also features an internal cast steel beam for maximum protection. The boot closes with 4 buckles, of which the top and bottom are reversed, giving a better statue and a more slim exterior. All buckles have double locking. Inside, the boot has a Poly-fabric lining and ankle protection with shock absorbing properties. The supplied inner sole reduces the inner dimensions of the boot one size. This allows you to buy one size larger for longer use. However, this does not include sizes 38, 39, 40.5 and 42.
