Boot fitters will tell you that custom- fitting a shell—matching plastic to foot shape— is the key to unlocking
a boot’s performance and fit potential. This year we tested several customizable shells with impressive results.
Fischer’s Vacuum technology compresses air bladders around a heat-moldable shell so it conforms precisely
to the wearer’s foot. (Shown: Fischer vacuum trinity 110, $700.) Salomon’s new 360 Custom Shell takes the company’s familiar moldable forefoot panels and constructs almost the entire lower boot out of the same customizable plastic. (Shown: salomon X-max 120, $750.)
Other approaches? Salt Lake microbrand DaleBoot measures your foot, then builds your custom shell, and Dalbello molds new KR 2 Pro and other shells with extra room for the four critical foot bulges that bootfitters most commonly deal with. These boots take factory-custom to
a new level.
