The Rossignol Pure Pro Heat is a great softer ski boot for someone looking to keep the comfort up all ski season! The Ultra warm Therm-Ic liner ups the stoke even more by having a built in heater (charger included) to make sure you stay warm all day long, no matter how cold the temps drop. The 70 flex index rating is great for someone looking to stay on top of the hill and crushing those turns out all day long.
