This adjustment in plastics also makes it slightly easier to get into the boot. We’ve seen these methods used quite a bit with touring boots to great success, so can totally get behind Salomon using this approach here. 

Next up is the easily-personalised fit which, you guessed it, can be adapted to match the unique contours of your feet. This includes the standard stuff like Salomon’s CustomFit 4D liners (which includes the mouldable Talyn material that helps to deliver a fantastic hug around your foot).

This customisation continues with Salomon’s Custom Shell HD, an aspect of the boot which essentially does the same as what goes on within the liner. By heating the shell of the boot for 10 minutes (drop your boots into a Salomon certified bootfitter to do this), the lower conforms to the shape of your foot, allowing for less pressure, more comfort and, most importantly for performance, a tighter fit.

So with all that customisable tech going into the boots, skiers can push the initial 98 mm last up to 104 mm, giving wider footed skiers the option of sizing up their boots to get the best performance-focused fit possible. While we’re not claiming boot customisation is a new thing to the market (far from it), it’s pretty impressive to see Salomon pack in this sheer level of customisation into a single boot.

All of this is moulded from a PU plastic that gives the same level of power and progressive flex that the initial S/Max boot range became so well-known for. In this case, the S/Pro Alpha offers a 120 flex rating that would be suitable for heavy intermediates to lightweight expert skiers. Thanks to the large amount of customisation on offer, the S/Pro Alpha 120 will also fit an impressive amount of foot shapes and volumes.
