This is the Lange Concept W RTL GW BOA alpine boot.

Designed for women, the boot combines high comfort with stable performance and easy adjustment via the BOA system. It has a roomy fit and a flex of 90 in the women's model and 110 in the men's model, which provides a good balance between comfort and control for both intermediate and advanced skiers. The GripWalk sole provides better grip when walking. Choose a boot that fits snugly around the foot and ankle for the best possible comfort and precision.
