Overlap Flow construction lets the shell open wide enough to step into easily, and the BOA H+1 closure wraps the forefoot in one geared motion rather than through a row of buckles. At 1,340 g per boot in a 27 with a 115 flex on a 101 mm last and 60 degrees of cuff rotation, it sits between a race boot and a freeride touring boot and skis harder than its weight suggests.\u003c\/p\u003e\n    \u003cdiv class=\"ccbb-expert-line\"\u003e\n      \u003cspan class=\"ccbb-expert-badge\"\u003eExpert Fit Review\u003c\/span\u003e\n      \u003cspan\u003eFit profile and recommendations reviewed by CCBB bootfitters.\u003c\/span\u003e\n    \u003c\/div\u003e\n  \u003c\/section\u003e\n  \u003csection class=\"ccbb-section\"\u003e\n    \u003ch3\u003eIs This the Right Boot for You?\u003c\/h3\u003e\n    \u003cdiv class=\"ccbb-grid ccbb-grid-2\"\u003e\n      \u003cdiv class=\"ccbb-card\"\u003e\n\u003cspan class=\"ccbb-card-title\"\u003eBest For\u003c\/span\u003e\n        \u003cdiv class=\"ccbb-quick-answer\"\u003eAdvanced backcountry skiers with low to medium-volume feet who want a light boot that still skis, on skis 85 to 105 mm underfoot, running pin bindings.\u003c\/div\u003e\n\u003c\/div\u003e\n      \u003cdiv class=\"ccbb-card\"\u003e\n\u003cspan class=\"ccbb-card-title\"\u003eConsider Another Boot If\u003c\/span\u003e\n        \u003cdiv class=\"ccbb-quick-answer\"\u003eYou want frame or MNC compatibility, or a wider fit.
