Advice : Use the foot sizer from SIDAS to help you find the right size
The FS 02 90 2027 is a unisex ski boot from the brand Phaenom, designed for the freestyle programme.
Featuring a 90 flex and a 100 mm last, it offers a balance between flexibility, comfort, and control for demanding use. Its hybrid HYBRID CABRIO / OVERLAP CONSTRUCTION combines the precision of a wallet-style boot with the progressive flex of a 3-piece cabrio shell. The two-hook closure system ensures secure support and precise adjustment.
The FS 02 LINER incorporates a shell-liner connection strap for easier handling, optional laces for a more precise and responsive fit, as well as a TPU stabiliser around the calf and shin to redistribute pressure. Its grid-patterned outsole, made from over 50% bio-based materials, effectively absorbs vibrations to reduce fatigue and improve comfort on landings. Additionally, the removable and interchangeable GripWalk soles guarantee excellent grip and natural walking.
Equipped with the PHAENOM STRAP to enhance rebound and flex control, and an adjustable forward lean set on three positions, this boot combines technical performance and durability thanks to manufacturing that incorporates up to 30% recycled materials and a detachable construction compliant with the Right To Repair.
