Here's what other sites are saying:
Every mountain's a big mountain when you're four-foot-nothin', so your junior freerider will have plenty of use for the mountain-crushing Volkl Shiro Jr. Kids' Ski. Built with the same Extended Low-Profile full rocker as the grown-up Shiro, the Shiro Jr.'s core sports dense ash underfoot and springy poplar in the tip and tail, making sure binding mounts are bomber and the ski stays light and poppy for littler legs. Volkl's Tough Box construction wraps the core in a composite and fiberglass sheath for extra durability and energy, too, so he'll be able to rip big lines and crush deep powder without having to work too hard.
