104mm last: Comfort is key for skiers matching up to this last width. * 45 Flex Index: These boots are very forgiving and are best suited for beginners and lower intermediate skiers who ski at slow to moderate speeds on groomed runs. * Tongue Pull: A loop of fabric at the top of the tongue helps in putting on and removing the boots. * 25mm strap: Velcro strap at the top of the boot that acts as an extra buckle, but without the hassle of a buckle. * Replaceable Toe and Heel Pads: This is a must-have for skiers that don"t live in ski in/ski out condos.
