Instead of having just one flex for all junior size groups, the Nordica Kids' Supercharger Jr. Ski Boot has a different flex index for each size group. This means your ripper gets great control on the mountain without the boot being just a little too stiff or too soft. The Supercharger Jr. Ski Boot's Comfort JR Fit provides a more tailored fit with better heel hold, and the fuzzy liner keeps your skier's feet warm. The Supercharger has a flex index of 55 (Mondo size 19.0-21.5), 60 (Mondo size 22.0-24.5) and 65 (Mondo size 25.0-28.0).
