The mission of NorthFit™ is to achieve the best, most precise fit between the human foot and footwear or the form on which a shoe is constructed. To achieve this we’ve partnered with English shoemakers with great experience, collaborated with The North Face® athletes and consulted with labs and think tanks to ensure that the most reliable, quantifiable data and recent studies are taken into account. Mountains of data go into each NorthFit™ implementation. For example, based on research, our shoemakers have adjusted for a larger toe box in our endurance running shoes to accommodate swelling. A study of almost 900 men and women revealed significant differences in ball and heel width, instep height, and width. As a result, The North Face® women’s footwear has a proportionately unique build from that for men. In this way, the outdoor athlete can trust that the most up-to-date scientific data and experience have been factored into the comfort and performance they can enjoy with NorthFit™.
