A ski boot should never slow you down. Tecnica knows this and that’s why their Mach1 85 is a great option for an advanced skier. The 85 flex makes it perfect for the control you are looking for on the slopes without sacrificing the comfort to keep you going. The Ultra Fit Liner won’t pack out too fast leaving you with a supportive fit. Quick Instep Max let’s you slide in easily (and out, if you ever decide to take them off). Look no further, a medium width, narrow calf, advanced skier will fit perfectly and comfortably in these babies. So keep on with your bad self and fly down that mountain.
