The Phaenom FS 01 80 A is designed to welcome skiers into the world of freeskiing with confidence, comfort, and control. Tuned specifically for intermediate all-mountain skiers and younger riders, this boot offers an approachable flex that makes progression feel natural—supportive enough to build good habits, forgiving enough to keep skiing fun. It’s a boot that encourages exploration, whether that means cruising groomers, dipping into variable snow, or trying something new for the first time.

Central to its feel is Phaenom’s hybrid cabrio / overlap construction, which blends the secure, close fit of an overlap boot with the smooth, progressive flex of a 3-piece design. This hybrid approach delivers predictable power transfer and gentle shock absorption, helping skiers stay balanced and composed through turns, terrain changes, and small landings. The clean two-buckle layout keeps things simple, intuitive, and easy to manage.

Comfort and longevity are built into every detail. The patent-pending Phaenom Strap adds elastic rebound and refined flex control, smoothing out skier input while reducing harsh impacts. Inside, a cushioned PU foam liner insole provides lasting comfort and support for full days on snow. Underfoot, the shock-absorbing GripWalk sole reduces vibration and fatigue while improving walking comfort off the skis. Finished in Phaenom’s purposeful all-black design, every component is engineered to be repairable, reusable, and recyclable—thoughtful design that grows with the skier.

Ski boots are sized in Mondopoint, based on the length of your foot in centimeters. The chart below is a general reference for converting between sizing systems.

This chart is not a fitting. The only way to know your ski boot size is to be fit in person, either with a Boot Fitting at our shop or from a professional fitting you have had elsewhere. Sizing, shape, and volume vary by brand and model, and a performance fit is snugger than your street shoe. Unworn boots can be returned under our return policy, but a boot that doesn't fit can be a big hassle for your trip if you haven't tried it on.

Half Sizes

Ski boots are built with one shell for each full and half size, so a 27 and a 27.5 are the same boot with a different liner or footboard. That is why sizes are listed together, like 27/27.5.

Very few models differ from this. Scarpa is the main exception, pairing sizes the other way (for example, 26.5/27 share a shell). When a model is sized differently, we call it out on that product's page.
