THE FS 01 100 A 2026
Exploring the world of freeskiing
The FS 01 100 A is designed for intermediate all-mountain skiers and younger riders who are exploring the world of freeskiing for the first time. With a more forgiving flex and a fixed 15° forward lean, this boot offers an exceptional balance of comfort and performance in a sleek, minimalist package. The hybrid cabrio/overlap construction provides efficient power transmission to the skis as well as shock absorption. The patent-pending Phaenom strap enhances rebound. Featuring fiberglass-reinforced plastic buckles and washers; the Liner 01 A; a standard boot-board; and a sealing band rather than a gaitor, the FS 01 100 A is the ideal choice for those who value simplicity and pure function.
Details
Fit: Last: 102mm – A wider last intended for average to wider and higher volume feet.
Flex: 100 – A medium flex designed for intermediate to advanced skiers.
Liner: Phaenom Liner 01 A – The Liner 01 A shares the shape and design of the premium Liner 6 01, offering top performance and comfort in a minimalist package. It omits the shock-absorbing outsole and lacing option, and features a fixed tongue, making it the ideal choice for those who value simplicity and pure function.
Recycled and Bio-Based Materials – The liner was designed to be as sustainable as possible without sacrificing performance.
Bio-Based Vibration Absorbing Outer Sole – The checkered print outer sole is designed to absorb high and low frequency vibrations coming up through the ski boot, making repeated landings more comfortable and reducing foot and leg fatigue throughout the day. The outer sole’s extra grip and design means it's tough enough to be worn alone at après, or on your journey to and from the ski hill. Made from a minimum of 50% bio-based content.
Calf Stabilizer – TPU plastic placed meticulously around the calf and shin area redistributes pressure to eliminate pressure points.
Shell Materials & Design: Hybrid Cabrio/Overlap Shell – The innovative hybrid cabrio/overlap shell features a distinctive and clean two-buckle design. It combines the best of both worlds: the close fit and edge control of the overlap, and the progressive flex of the 3-piece.
All-Black Design – The sleek all-black design supports restoration and reuse of the boot and its parts. Each element of this product — from panels to buckles to straps and screws — is designed to be repairable and recyclable.
Recycled Materials – Phaenom boots are designed to be as sustainable as possible without sacrificing performance.
