Phaenom fs 01 100 Ski Boot 2025

The Phaenom fs 01 100 ski boot is the all-mountain freeski boot designed to achieve flex perfection, power transmission and shock absorption. The fs 01 100 is designed for those seeking both comfort and performance. It offers a more forgiving yet responsive feel. The innovative hybrid cabrio / overlap construction combines the best of both worlds: the close fit and edge control of the overlap, and the progressive flex of the 3-piece. Paired with the patent-pending phaenom strap, the fs 01 100 provides rebound, shock absorption and exceptional flex control. The elasticity of the strap generates tangible rebound through your turns, for increased power transmission, turn initiation precision, comfort and predictability. Designed for customization, the boot comes with three different inserts (flip chips) that allow forward lean angles of 13°, 15°, and 17°. 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. For accurate foot length measurement we recommend following these 3 steps. step 01: Put a piece of blank paper under your feet. Stand up straight and have your heel lightly touching against the wall. step 02: Have someone mark the end of the longest toe on the sheet with a pen or pencil. Afterwards measure the distance from the end of the page to the mark on the paper. step 03: Repeat the steps for your other foot and compare it with our size chart. size chart*: shoe size (US) Men shoe size (US) Women shoe size EU shoe size UK foot length range (mm) comfort fit performance fit 4 5 36 3 215 - 224 22/22.5 21/21.5 5 6 37.5 4 225 - 234 23/23.5 22/22.5 6 7 39 5 235 - 244 24/24.5 23/23.5 7 8 40 6 245 - 254 25/25.5 24/24.5 8 9 41.5 7 255 - 264 26/26.5 25/25.5 9 10 42.5 8 265 - 274 27/27.5 26/26.5 10 11 44 9 275 - 284 28/28.5 27/27.5 11 12 45 10 285 - 294 29/29.5 28/28.5 *In our size chart, your shoe size corresponds to a mondo point. The mondo point is an international sizing scale used for ski boots. It has about a 1cm difference between each size. The mondo size of the boot that corresponds with your US size should give you a comfortable fit. If you prefer a tighter fit and want a quicker response from your boots, and/or have a narrower foot we recommend going down a size. We always recommend consulting with a bootfitter to help you decide what works best for you. example: Jordan has measured their feet and found that the left foot is 252mm long, while the right foot is 254mm. Knowing that they generally prefer their boots to fit tightly, they use the length of their shorter foot, 252mm, as a reference for choosing their ski boot size. Consulting the phaenom size chart, Jordan can select between a 25/.5 for a comfort fit or a 24/.5 for a performance fit. Given that they ski more than 30 days a season and their feet are on the narrower side, they decide to go with the performance fit at size 24/.5. This choice ensures a snug fit, minimizing movement inside the boot for better control on the slopes.
