Alpina Sizing : Alpina boots mondo to US shoe sizing conversion is a little different from most other brands. Please make sure to refer to the sizing chart in order to find your correct size.
Rear Entry Shell Design: This boot features a true Rear entry shell design, just like from the 80s. No hybrid almost rear-entry buckle systems. Just a single ratchet-tightening buckle and a massive rear opening.
40 Flex Rating: 40 Flex for an adult boot is VERY soft, and indicates that this boot is meant for beginners and very casual cruiser skiers. If this is a junior boot, 40 flex is stiffer than average and will be meant for strong kid skiers.
High Thermal: This boot features extra thermal material in the toe of the boot to keep your foot a little extra warm.
Replaceable Toe and Heel Pads: This is a must-have for skiers that don't live in ski in/ski out condos. When your ski tech tells you that you have to buy new boots because the soles are worn down too much, just laugh at him and tell him to order you a new set of sole plates.
105mm Last Width: This boot has a 105mm width in the forefoot area, and is one of the widest available for ski boots. This width gives wide-footed skiers a chance to enjoy skiing, instead of cramping up and getting pressure points the whole day. Average width skiers will find that this width is very comfortable and warm.
