The Roxa R/Fit Pro 85 Womens Ski Boot is the perfect option for intermediate to advanced level ladies with a medium forefoot and medium calf volume. The new overlapping shell and cuff design deliver consistent flex for better power transmission as you drive into the boots. The OptiLock buckle allows you to fine tune the feel of the buckle over the instep area for a comfortable fit, avoiding any pinching or uncomfortable spots. The liner is made up of super plush EVA foam for extended comfort while the women's specific cuff sits lower to accommodate women's different calf shapes for a better fit. Thanks to BioFit technology, the shell and liner can both be heat formed for a custom feel to your foot after taking them into a qualified ski shop.
