Roces Adjustable Boot Liner

All about the Roces adjustable ski boot liner and how it works.

Liner Bellows System

The staple feature of IDEA's liner is a peculiar and unique adjusting system which, unlike most of the 'fake' systems available today pretending to work as such, performs its task through a bellowing device allowing a real growth of the liner respecting the natural development of the foot. The Liner Bellows System (LBS) has been devised to avoid any pressure on heel, toes or whatsoever uncomfortable feeling wherever on any foot.

In fact the natural/resting position of the liner is with the bellows extended to the biggest size, while shortening the shell makes the bellows compress into smaller sizes. It is easily understood that it is not the foot who makes the liner growing size system work but the shell itself.
