While the Lily borrows many of the best fit and comfort elements from the top-notch Salomon Women's Optima it features a slightly looser versatile flex that works better for advanced and expert freestyle riders. It features female-specific fit refinements like a stretch calf back panel for your lower calves and a unique anatomical mold. Created with an anatomic Biocage liner the Lily has a heat moldable Bio custom fit and Salomon's Comform'able footbed with low pressure massage bubbles in the footbed. Even with the massage bubbles the footbed does offer plenty of support along key foot areas for optimized performance. Up top you'll find a Powerlace pro soft lacing system with a customizable dual zone lace system that has a user-friendly blocking system that expedites lace adjustments faster than the normal Powerlace Pro. There's also a one-pull quicklace feature that simplifies the closure. Like other Salomon women's boots the Lily has a Toasty-toes internal fur (faux fur that is) lining material that insulates far better than the unisex boots. Beneath the boot is an ultra-sensitive Sensiflex outsole with rubber metatarsus pods that work as sensors between your board and the bottoms of your feet. Like the Optima and Fusion Series boots for both men and women the Lily also features Salomon's exclusive ADIPRENE compound to help absorb impacts from big air landings.
