New Balance is the only manufacturer to offer a majority of shoe models in multiple widths, from narrow 2A to extra-extra-wide 6E. Just like people, feet come in all shapes. New Balance knows that proper fit means multiple widths, not just multiple sizes.

There is a 0.5 inch difference between a B and D width and a 0.4 inch difference between a 4E and 6E. It is important to note that this is the maximum difference in width. This occurs across the ball of the foot. There is less of a difference towards the tip of the shoe and towards the heel.
A "Last" is a wood, plastic or metal model of the foot on which shoes are constructed. The shape of the last affects the width, length and fit of the shoe. Each New Balance Last is engineered to provide a unique fit and size profile to fit a unique foot shape. The most popular lasts are "SL-1" and "SL-2", a standard straight last and one with a higher instep and deeper toe box.
It's the natural rolling of the foot when walking at any pace faster than mall walking. (When mall walking, one walks heel to toe at a very slow pace.) The way one actually walks is by hitting the outside of the heel and gently rolling in, pushing off your big toe on the inside. That natural roll is called pronating.

If you step on the outside, curl right in and wind up on the inside of your foot - that's over-pronating. New Balance builds up the arch on specific models to force your foot out so as not to let your whole arch collapse too soon. Other people hit on the outside of their heel and stay on the outside of their foot as they walk - like a duck almost - that's called under-pronating or supinating.
We know that shoe size has nothing to do with a woman's sense of style. Without the elegance, excitement, and romance found in standard sizes, women who wear uncommon sizes are unable to enjoy the same style and glamour. We believe women want shoes that look great and feel just as good. They want Anne Klein, Joan & David, Naturalizer. We will never even carry a style unless it comes at least to size 12. We see this as both a promise to our customers and a political position in the women's fashion shoe industry.We are dedicated to nurturing relationships with shoe companies in order to maintain a selection that is "haute", spicy and sure to please!
