This just great for being a boot that will take you anywhere. They have a good flex where you will be in control and safer for when you're going moguls and steep runs where you need to be stable but they won't be too stiff for when you want to relax and enjoy the powder. And they will be a snug comfortable fit.

This boot offers a great blend of comfort and performance. Lange has a reputation for having tight fitting boots and this offers a wider instep for more comfort.
