Downsizing, Redefined: Compact Power Without Compromise
For 26/27, we’ve reengineered ski boot sizing to set a new benchmark in performance and fit. Our innovative last design runs longer than industry standards, creating more usable space inside without adding bulk.
This lets us fit a true 26 mondo size into a 295 mm sole length, a downsizing milestone that delivers a sleeker, more responsive boot without sacrificing comfort. The result is reduced swing weight, quicker reaction, and greater control, all in a smaller, more efficient package.

Product Description
Built for skiers who demand consistent energy transfer from first run to last, the PHAENOM fs 02 130 fuses a hybrid cabrio/overlap shell with the brand's signature recyclable strap system for a flex profile that feels the same at -15°C as it does in spring corn. The TPU+ shell holds its character regardless of temperature, while the 100 mm last delivers precise fit without sacrifice. For performance-oriented all-mountain freeskiers who refuse to compromise.
Product Details
| Shell / Cuff / Tongue Material | TPU+: a newly engineered thermoplastic polyurethane exclusive to the 130-flex models. Temperature-stable, it delivers a consistent flex feel and response in all conditions, from hard ice to spring corn |
| Hybrid Cabrio / Overlap Construction | Distinctive two-buckle hybrid construction combining the precise fit and edge control of an overlap boot with the progressive flex of a three-piece cabrio design |
| Progressive Flex | Driven by the hybrid cabrio/overlap construction paired with the Phaenom Strap: provides rebound, shock absorption, and flex control from a single recyclable material for an exceptional, unique flex progression |
| Phaenom Strap (patent pending) | 100% recycled nylon strap delivering tangible rebound through turns for increased energy transmission, precise turn initiation, comfort, and predictability |
| Fit Profile | 100 mm last: true mid-volume fit based on industry sizing standards for accurate size selection and a precise, performance-oriented hold |
| Upper Cuff | Overlap construction wrapping the lower leg for precise fit and exceptional energy transmission to the skis |
| Shell Tongue | Low-cut shell tongue: eases entry, protects the open zone above the foot without crowding the toe box, and absorbs impact |
| Lower Shell | Mid-volume toe box with a heel pocket that locks the heel and transfers energy directly to the skis; reshaped opening with a higher instep |
| Adjustable Forward Lean | Three interchangeable flip-chip inserts: 13°, 15° (default), 17° |
| Interchangeable Anatomic Spoilers | Customizable spoilers for precise ergonomic calf hold and desired forward-lean angle; height-adjustable in 5 mm increments |
| Easy Entry System | Low-friction liner interior, single-hand tongue leash connecting shell to liner, and flap-to-tongue link keeping components aligned during entry and exit |
| Oversized Buckles | Clean design, high durability, and easy operation; 100% recyclable and repairable; aluminum construction |

| Eco Materials | Shell: 15–30% recycled TPU; insoles: 30% recycled EVA |
| Liner: liner fs 02 | Weight: 460 g · GridSkin™: lightweight structural mesh laminated on the outside of the liner for enhanced durability, abrasion resistance, and flexibility while maintaining comfort and modern aesthetics · PillowFoam™: 3 mm self-molding PU foam layer on the inside of the liner that gently conforms to the foot for an accommodating step-in, optimized fit, and all-day comfort · Tongue: adjustable triple-layer · Lacing: quick lacing · Shock Absorbing Sole: checkered outsole absorbing high- and low-frequency vibrations, reducing foot and leg fatigue, and making landings more comfortable; minimum 50% bio-based content; usable on its own as an après-ski sole |

Fs 02 130 Ski Boots 2027 FAQ
Who is the fs 02 130 for — is a 130 flex too stiff for an intermediate skier?
The fs 02 130 is aimed at performance-oriented all-mountain freeskiers who want precision and powerful energy transmission on hardpack, crud, and variable conditions. A 130 flex is a stiff rating, best suited for strong intermediates to advanced riders who can drive the boot actively.
What is TPU+ and why does it matter for a stiff boot?
TPU+ is PHAENOM's newly engineered shell material, exclusive to the 130 flex model. It's temperature-stable, meaning the flex stays consistent whether you're skiing on icy morning groomers or wet spring corn. Standard TPU stiffens in the cold and softens in warmth; TPU+ eliminates that variability.
I ski hard every day — will this boot feel the same on day 50 as on day 1?
The TPU+ shell in the fs 02 130 is engineered for consistent flex across temperature swings. Combined with aluminum oversized buckles (100% recyclable and repairable) and a GridSkin mesh-reinforced liner, the construction is built to hold its shape and performance across a full season of hard use.
These boots seem compact for a 130 — what's the downsizing innovation about?
PHAENOM engineered a true mondo 26 foot to fit in a 295 mm sole length, which is longer than the industry standard for that volume. The result is reduced swing weight, faster edge-to-edge response, and a more compact package without sacrificing volume or comfort in the toe box.
How do I size these correctly — especially with the downsizing design?
Measure your foot length in mm and use the size table directly. A foot of 257-266 mm maps to mondo 26/26.5 and a 295 mm sole, 100 mm last. The downsizing design affects shell length, not fit volume, so standard mondo conversion still applies. Don't size by street shoe alone.
Will these boots work with my current bindings?
Yes. The fs 02 130 comes with GripWalk soles (ISO 23223), compatible with GripWalk-ready and most modern alpine bindings. If your setup is strictly ISO 5355 alpine, you can swap to the Alpine Sole Pads Set sold separately by PHAENOM.
What does the Phaenom Strap contribute at a 130 flex?
The Phaenom Strap (patent pending) is a 100% recycled nylon strap built into the construction. At 130 flex, it smooths the progressive load curve so the boot doesn't go from soft to a wall. It also delivers rebound out of the turn and absorbs chop, keeping the ride controlled rather than jarring.
Can I adjust the forward lean, and what comes in the box?
Yes. Three interchangeable flip chips are included, setting forward lean at 13, 15 (default), or 17 degrees. The box also contains an anatomic spoiler (adjustable in 5 mm height increments), a 2 mm spacer, and quick laces for the liner.
