The Hawx Magna 100 is a great fit for strong intermediate to advanced skiers with a medium to wide foot shape that have never been able to get comfortable in ski boots. Atomic's Memory Fit Shell can be heat molded by an authorized Atomic Dealer for a true custom fit. The shell can be heated in a special oven. Once the shell is warm it placed on your foot. When the shell cools, it can adapt the shape of your foot. 3M Thinsulate Insulation is extra warm on cold days. If you want a ski boot that will be very easy to fit for your foot, the Atomic Hawx Magna will be the perfect choice for you.
