The Nitro MICRO CHARGER is made for kids who like to be independent and don't need their parents to strap them to the board. Ideal for the first steps towards a new personality. The QUICK-FIT base is easily adjustable and is able to respond to rapidly growing feet. The Perfect FIT comfortable buckle with a large cut-out, which increases the flexibility and the adhesion to the boot, has a ratchet with a large lever that is very easy to tighten.
