The industry guesses your flex by ability level. That's wrong. Skiglede measures how you actually ski and calculates the exact flex your body needs.
The name
It's a Norwegian word with no direct English translation — and that's exactly the point. Ski you already know. Glede is the Norwegian word for joy, delight, happiness. Together they form something that four words alone can't quite capture.
For some, it's the first turn in untracked powder — the silence before the spray, the feeling of floating that you spend the whole summer chasing.
For others, it's après-ski — still in your boots, sun on your face, cold beer on the terrace with the mountain right there in front of you, and nowhere else in the world you need to be.
It's the quick lunch stop halfway down. A hot dog in the mountain sun, skis planted in the snow beside you, five minutes of breathing cold air and doing absolutely nothing else.
And then there's the little boy — snow piled on his knitted hat, cheeks red — who has been in the garden since before breakfast and absolutely refuses to come inside. He doesn't know the word yet. But he knows the feeling.
We named this app after it because your version of skiglede is worth protecting. Bad boots don't just hurt your feet — they interrupt it. They turn a powder run into a painful slog. They make après-ski feel like relief rather than a celebration.
Skiglede the app exists so your equipment never gets in the way of why you actually ski.
The problem
Walk into any ski shop and they'll fit you by "ability level" — beginner, intermediate, expert. But flex should be based on physics: your weight, your height, and how fast you actually ski. Two "expert" skiers can need completely different boots.
Ignores your actual body and speed
Calculated from mass, speed, and height
How it works
Height, weight, ski radius, and your current boot flex. Takes 30 seconds.
Record your speed on 3 runs at your natural pace. Just how you ski.
We calculate centripetal force, torque, and lever arm to give you an exact flex recommendation and matching boots.
The technology
Skiglede uses a calibrated biomechanical model that calculates the forces your boot must resist when you carve at speed. It's the same physics ski racers use — now available to everyone.
Testing boots since 2004. Analysing with sensors since 2009. Rooted in published sports technology research.
Lateral G-force, angular velocity, and dynamic load factor — derived from your measured speed and turn radius.
Lever arm length, shin-to-cuff contact angle, and stance mechanics scale with your body dimensions.
Resultant boot force, estimated torque, and kinetic energy — the total load your boot must handle.
The foundation
The formula inside Skiglede wasn't written in a day. It was built run by run — with pressure sensors, force plates, and GPS on real skiers across real mountains. Every iteration was tested, calibrated, and refined against measured data before it shipped.
40 years as a boot fitter. 12 years of active sensor measurement. That's what's behind your flex number.
