While rental ski boots are fine if you don’t ski a ton — and you’re okay with boots that are a hair too loose or too tight — if you go on more than a few ski trips each year, you are usually better off buying your own boots. Like your favorite skis and warm yet stylish jacket, the right boots with the just-right fit can make a huge difference. “Ski boots are by far the most important piece of equipment on the slopes,” says Woodrow Berry, retail manager at Big Sky Resort. This is because, as Trevor Livingston, an account manager at Backcountry, explains, “your boot is in place to transfer all the energy that you’re generating with your body and your legs down to your skis.”

Choosing boots involves weighing the balance between comfort and performance. “You have to be prepared for a level of comfort that matches what you want to do with the skis,” says Michael Rogan, coach of the Professional Ski Instructors of America & American Association of Snowboard Instructors (PSIA-AASI) Alpine Team, a hand-selected group of the country’s best ski instructors. A softer boot that’s more comfortable won’t be as responsive to your movements, which is often fine for new skiers, but more advanced skiers may want stiffer boots that pick up on all their precise maneuvers. You can get a sense of a boot’s stiffness by the flex index, a number ranging from 50 (supersoft but not that responsive) to 130 (very rigid and reactive). Flex is also highly influenced by your weight: The larger your body size, the stiffer boot you’ll be able to maneuver, so men can typically wear boots with a higher flex index than women of the same ability level.

Getting the right fit is also crucial — and something you could only hope to luck into with rentals. “Boots should fit like a firm handshake. Not too loose and not a death grip,” says Sean Meszkat, a senior manager within Vail Resorts’ retail division. “Too firm and you’ll be aching; too comfortable and you’ll suffer from a lack of support and comfort.” Our experts stress that you should look for a boot with a heat-moldable lining, so you can get it to match the exact shape of your foot, and to see an expert boot fitter who can make further modifications to the plastic shell for a personalized fit.

“The Salomon S/Pro 100 is the No. 1 model in the U.S. and Canada,” according to Jim Fuller, divisional merchandise manager at Vail Resorts. Hovering around the midpoint of the flex spectrum (it comes in softer and firmer versions as well), these are ideal for intermediate skiers who want performance benefits but don’t want a boot that’s extremely stiff. Fuller especially loves how customizable these boots are, with moldable liners and heat-moldable custom shells that allow you to reshape the outer plastic.
