When purchasing anything that will be worn, the two most important things to consider are fit and comfort. There is no exception when buying ski boots. While there are other factors, fit and comfort come first.
If your ski boots don't fit properly, you will have difficulty skiing. If the ski boots are too large, your feet will move around inside them, making maneuvering difficult. If too small, your feet will not only be uncomfortable, but the boots may not be flexible enough for optimum movement.
Choosing comfortable ski boots is important, because you will spend a lot of time on your feet. You do not want to hit the slopes for the day, only to find that your feet hurt after a short time. When you are buying ski boots, you should try to purchase them in a shop that is willing to let you try them out first.
You may want to walk around in a pair of ski boots for several hours before buying them to make sure they are comfortable after extended wear. If you purchase ski boots at a resort, in many cases, you may be allowed to try them on the slopes and return them if you are not satisfied. Ask about this option before you make a purchase.
If you are concerned about warmth, some ski boots come with built in foot warmers. Many expert skiers advise against these styles, however, because the warmers can take up a lot of space in the boots. Instead, they suggest purchasing quality ski socks. The choice is up to you, but most experts insist that if you are active on the slopes, your feet will not get cold. You can always purchase separate warmers and add them later if you decide you need them.
Another thing to ask about when looking for ski boots is custom fitted insoles. They don't add much cost and are well worth the price and the time it takes to have them fitted. Since ski boots transform foot and leg motion into ski movement, it is very important that boots fit snugly but are not too tight. A good fit should give plenty of support while still offering the necessary flexibility.
