The Dalbello Krypton ID series is designed to undergo thermal or heat molding before a skier can use them. Professional boot-fitters are required to execute this heat molding by using the appropriate equipment. Searching for and setting up with a knowledgeable boot fitter can take time. This can prove to be an unwanted hassle for active skiers who prefer to get up and go with their ski boots without going through any other processes.
Some skiers who tested and reviewed the boots think they're not visually appealing when compared with other ski boots. Women's boots (Storm ID model) are uncomfortably tight fitting at the start, necessitating pulling the thermal liners out to get a comfortable, snug fit. Some who've tried models of Dalbello Krypton find the inside of the boot to be sharp enough to cut flesh.
After a relatively small number of uses, the liner shows signs of wear and tear. Some users remarked that it starts to detach from the foam after constant use. Using Intuition liners as replacements only seems to make the shoes voluminous and uncomfortable.
Other downsides to the Dalbello Kryptons include the liner not having enough rigidity and folding too easily; pressure issues in the ankle area; heel/toe pieces can't be replaced; insufficient sole modifications; the Velcro on the booster straps have snow trekking issues; and metal strap buckles at the back can get them stuck on ski lift chairs.
