Last: 98 mm – Narrow last for slim to normal width feet with normal volume. Can be heat molded using the custom heat molding process to approximately 104mm in the forefoot

Custom Shell HD – Salomon's proven heat molding process makes boot fitting most feet quick and easy - the latest Custom Shell HD version is even quicker to mold than before. The thinner wall construction and new shell materials allow the foot to be closer to the shell and provide enhanced sensations, more power and direction energy transmission

3D Instep Shell – This new construction refers to the construction of the lower shell. The thinner plastic and strategic positioning of the forefoot buckle deliver less pressure on the top of your foot, make for easier step in and out, and ensures stronger heel lock without putting unnecessary pressure on your foot

Flex Adjuster – The Flex Adjuster allows you to boost or smooth your flex

Flex: 100 – A medium flex for intermediate to advanced skiers
