Ski Boot Flex
How forgiving or stiff the boot feels when you flex forward
Overview
The Ultra 85 W is an excellent choice for intermediate or lighter skiers with slightly narrower-than-average feet, or those who prefer the snug sensation of a tighter boot without requiring top-end performance. Its lighter construction, utilizing Atomic's Prolite design principle and Energy Backbone, ensures that unnecessary weight is kept to a minimum while retaining the right amount of power.

Prolite
Prolite is a way of building skis and boots that turns traditional thinking on its head. Instead of starting with a standard construction and cutting material away to save weight, Prolite does the opposite. It starts with the slimmest possible profile and then it builds up reinforcements in key areas where strength is needed.
