Salomon's Impact CS 9 boot brings together the popular Salomon Impact last with the equally popular
Custom Shell technology.
That means these boots feature a 100mm last that can be custom molded to around 106mm
at it's widest (that is really wide!).
Moving beyond the Custom Shell, the liner is also heat-moldable and will custom fit to your foot as you ski in it.
These boots have a 110 flex rating, which is a good flex for any aggressive skiier from the upper-intermediate to expert level.
