Sizing Tips:

New Balance earned their position as the leader in Total Fit(TM) by offering more fit combinations than any other footwear company. In addition to shoe length and width, they use a shoe last. A shoe last is a 360 degree model of the foot used to create each shoe's heel width, instep height, toe box width and toe box depth. Though it's not the primary factor, in conjunction with length and width, the shoe last helps you achieve the best possible fit.
