With a flex of 115 this Speedmachine 3 sits at the top of our women’s boot range. There’s a lot of innovation packed into this model such as the 3Force construction, a lightweight honeycomb design that provides lateral stiffness and linear power to the ski for ultimate control and feedback. This is effectively blended with softer plastics to wrap the foot and deliver comfort with ease of entry, something that other performance boots can compromise on. A pre-shaped 3D Cork Fit W PrimaLoft liner makes sure the boot feels, and fits, great straight out of the box. The liner can also be moulded to maximise comfort, while the cork adds rear foot hold and the PrimaLoft insulation ensures feet stay warm. Infrared technology on the shell makes sure the boot can be customised quickly and effectively in-store to add extra shape where needed. The ultimate choice for advanced and expert skiers wanting a medium width boot.
