When it comes to heat moldable liners for ski boots, the original is still the best. The Intuition Luxury Liner is a classic, tongue style liner with medium density foam designed for both superior comfort and high performance. It features a medium stiffness tongue, optional speed lace system, and of course, Intuition's durable closed cell EVA foam throughout. The Luxury uses a thick and comfortable 9 mm sole, so some footbeds may not be compatible or pressure on the instep may be increased. Intuition recommends "sizing up" with the Luxury Liner - if your boot is a 26.5 mondopoint, for instance, order the 27 in the Luxury. evo recommends having this liner heat molded by a professional bootfitter if possible.
