The Women’s Surge features all the same stiff and powerful features as our standard Surge - solid baseplate, stiff highback, supportive ankle strap - but sized specifically for women’s boots. Shorter and narrower baseplates fit snug and comfortably, accommodating down to a size 5 US (22 Mondo) boot. Lower and more compact heel loops move the ankle strap mounting point down to hit the sweet spot over your boot while positioning the highbacks lower on the leg for a better calf fit. All Women's Surge bindings incorporate our industry-leading Tesla T1 technology. Every piece of this binding is made in-house with the exception of a few screws and the buckles!
