Redefining Freedom on the Slopes
Ski boots are a vital link between the skier and the terrain, but traditional designs often sacrifice comfort and adaptability for performance. This project redesigned the ski boot using a modular, lightweight and ergonomic approach.

Design Brief
Designed to enhance the adaptability, comfort, and sustainability of ski boots for modern adventurers, this concept addresses key pain points—difficult entry and removal, poor walking comfort, and low recyclability—through an optimized closure system, shock-absorbing outsole, modular liner customization, and a fully sustainable material strategy.
Observational
Persona

Alvin
Weekend Warrior
skis a few weekends each season. Needs boots that are easy to put on, comfortable for short walks, and stylish off the slopes. Struggles with stiff, hard-to-adjust boots and foot fatigue after a few hours.

Arky
Backcountry Explorer
outdoor guide skiing in remote areas. Needs lightweight, thermally adaptable boots with a secure fit and sustainable materials. Frustrate

Liam
Ski Instructor
teaches skiing over 100 days a year. Needs durable, shock-absorbing boots that adjust quickly between lessons. Faces constant foot fatigue and rapid liner wear.
Biomechanics Research
Skiing demands rigid forward support, while walking requires greater ankle mobility — highlighting the need for a design that seamlessly adapts between stability and flexibility.
