The X3 Jr comes with the world cup advanced shell technology, which is geared towards controlling back support, the torsion control of the boot, and the body positioning into the boot. The Salomon X3 Jr also comes with a mono-material PP upper cuff, which is made from the soft and light polypropylene, which has a high UVA resistance and offers a good quality and durability to this ski boot. This race boot also features 4 micro titanium buckles, which is a light and stiff buckle used to micro adjust the length of the buckles for a presice and personalized closure.
This boot is comparable to the Salomon X3 CS boot, which is geared towards adults and features a lot of the same qualities, coming with the My Custom Fit Pro liner.
