About this product

The Phaenom fs 01 90 is an all-mountain ski boot built for freeride and powder terrain, carrying a flex index of 90 and a 102mm last width that suits a range of foot shapes. Its hybrid cabrio/overlap construction blends the close fit and edge control of a traditional overlap shell with the progressive flex feel of a 3-piece design. The patent-pending Phaenom strap adds rebound and shock absorption through turns, improving power transmission and turn initiation. Two aluminum buckles and an elastic strap liner closure keep the fit secure, while the thermo-moldable liner, made from 50% recycled fabrics, can be heat-fitted for a personalized feel. Three interchangeable flip-chip inserts let skiers dial in forward lean at 13, 15, or 17 degrees. The GripWalk sole (ISO 23223 compatible) makes walking on hard surfaces more natural. The TPU shell is finished in all-black, and every component, from buckles to panels, is designed with repairability and recyclability in mind.

What people are saying

Reviewers consistently praise the Phaenom FS 01 90 for its innovative hybrid cabrio/overlap construction, which delivers a progressive, lively flex with strong power transmission and shock absorption. The patent-pending elastic strap earns repeated mention for generating noticeable rebound through turns. The two-buckle simplicity, comfortable out-of-the-box feel, and exceptional build quality are also recurring highlights, with testers noting the boots feel stiffer and better made than their flex rating suggests. Sustainability credentials, including recycled materials and a fully modular, screw-together design for easy part replacement, are widely appreciated. The most common criticism centers on fit: the wide 102mm last suits average to wider feet well, but skiers with narrow or low-volume feet may find the boot sloppy and will likely need professional bootfitting or heat molding to get a proper fit.
