Otherwise, the two ski boots sport the same features, including a 103mm last and an articulate heel area as well as a Comfort Fit liner.
The Concept 80's 80 flex index allows for a larger amount of bend, making it less stiff and more comfortable therefore making it best suited for beginners. Its 103mm last and an articulate heel area also make the Concept 80 more comfortable, providing a higher degree of boot movement and flexibility. Meanwhile, the Concept 80's Comfort Fit liner provides a more comfortable skiing experience for the user's feet and ankles, even during longer sessions.
