Most ski boots are made with anywhere from two to four buckles, and buckles help you tighten and adjust the outer shell of the boot to help with boot fit and comfort. It’s better to buy ski boots that have metal buckles since those buckles will be stronger and last longer.
Some brands have micro-adjustable buckles, which help make it even easier to fit the boot to your feet better. These buckles spin and lengthen or shorten their shaft, which helps make the adjustment process easier. Also, make sure you get a pair of boots with buckles that are easy to use while you still have your gloves on since this will save you time and help you avoid having to touch icy, cold boots with your bare hands.
