Buy boots now › Boots are the conductors between your legs and your skis. A sloppy fit and— zap—the lights go out. (Frankly, we’re surprised newbies in rental “mush buckets” ever stick with the sport.) Boots are the single most important piece of ski gear, and getting the right pair will make you a better skier.
Now some tips. First, go to several shops you trust, preferably when you can get undivided attention. The salesperson should “shell fit” you, removing the liner and measuring heel space. (Experts should have a finger and a half between the heel and the back of the shell.)
Try on as many brands and models as possible in your size and assess them when flexed—they’ll likely feel too tight when you’re upright. (Never buy too big for comfort’s sake.) When you get a good fit, find an appropriate flex within that line. You should be able to bend your knees without being knocked rearward.
Flex ratings › There’s no industry standard for measuring flex, but the number is still a good indicator. Pick a range and feel-test several boots within it.
