Average instep height but due to the sensitive nature of this area of the foot as many blood vessels flow through here it's still important to make sure the blood is not restricted.
For the skier who often struggles to find shoes that are wide enough. Typically buys EE or EEE footwear.
For a blend of increased power to be transmitted to the ski while maintaining sufficient ankle flex to swallow up varied terrain.
Boot Calf Volume
Best suited for either larger or perhaps a lower calf often referred to as an athletic calf. This larger opening of the boot is designed to accommodate this area for better comfort while not impeding the performance.
