The Dalbello KR Fusion I.D. boots are some of the most unique designs available today. Building off of their extremely successful three piece shell design (the tongue, lower boot, upper boot) the Fusion features a more anatomically correct shell shape than past Krypton models. Clocking in at a 120 flex rating that can be made lower or higher by switching the tongues, these boots are designed for aggressive skiers. This model comes equipped with an ID Intuition heat mold-able liner for that extra precise fit that is necessary for higher skiing ability levels.
