For example, a 25.5 and 26.0 are the same shell size but the respective liners come pre-molded to the half size.Some skiers may want to downsize up to 1 full Mondo size, depending upon personal preference.Age Group: AdultOriginal Colour by Producer: Carbon/OrangeColour: BlackColour: OrangeMade in: ItalyFlex: 100Gender: MaleRange of Motion: 72°Season: 2021/2022Ski Boot Buckles: 1 Buckle + Boa Closure SystemSki Boot Last: 100 mmSki Boots Category: Ski TouringType of Sole: Vibram UFO RSTechnology: RECCOTechnology: Quick Step InTechnology: Intuition LinerTechnology: Carbon Grilamid ShellTechnology: Speed LockTechnology: BOATechnology: VibramWalk Mode: YesWeight: 990 gSelect Size: 28.0Model Year: 21/22Size: 28,0
