Last: 102 mm – Designed for wider and higher volume feet. Extra space at the forefront and instep, plus a wide tongue and fluted calf.

Memory Fit – Advanced heat-fitting technology creates a fully personalized shell, cuff and liner in minutes. The key is Memolink, Atomic's special additive that improves the moldability and stretch of their plastics. Expansion can be up to 6mm forefoot width and up to 10mm ankle width, resulting in a permanent and complete anatomical fit in minutes. See your bootfitter for details.

Adaptive Fit Cuff System – These boots come with a special spoiler in the back of the cuff. If you want a classic, cozy fit around the calf you can just leave the spoiler in. If you want more volume you can take the spoiler out. This makes the boot cuff slightly lower at the back, more tuliped and more open (equivalent to one cuff size larger). It's quick, easy and you don't need tools.

3M™ Thinsulate™ Insulation – Keeps feet warm and responsive even in extremely cold and damp conditions.

3D Stretch Toe Box – Asymmetrically shaped for left and right, the new 3D Stretch Toe Box takes first fit and customization potential to the next level. Its ‘Big Toe Friendly’ construction maximizes the liner’s available length allowing for a little extra stretch when important millimeters are required to achieve the perfect fit.

Prolite – 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 builds up reinforcements in key areas where strength is needed - like the Energy Backbone down each boot spine.
