Shoe Lasts

New Balance earned our position as the leader in shoe fit by offering more fit combinations than any other footwear company. In addition to shoe length and width, we 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 our customers achieve the best possible fit.
