The most important clinical decision with Shoe Width Guide isn’t which treatment to start with — it’s identifying the correct subtype. That changes everything. Call (810) 206-1402.

Understanding Shoe Width Codes
Shoe width in the US is designated by letters, with each letter representing approximately 3–4mm of additional width across the forefoot. For men: B=narrow, D=medium (standard), 2E=wide, 4E=extra-wide, 6E=extra-extra-wide. For women: AA=narrow, B=medium (standard), D=wide, 2E=extra-wide.
Most shoe stores stock only medium width (D for men, B for women) as their standard inventory. This means a significant portion of the population — particularly those with bunions, wide forefeet, or edema — are wearing shoes that are functionally too narrow.
European sizing uses a single number without width designation — making width determination reliant on the specific brand’s last (the foot-shaped form used to construct the shoe). This is a significant limitation of European footwear for patients with wide-width needs.
How to Measure Your Foot Width
The most accurate method uses a Brannock device — the metal measuring tool found at shoe stores. Stand on the Brannock device with full body weight and measure both foot length (heel to longest toe) and width (at the widest point of the forefoot). Do this at the end of the day when feet are at their widest due to daily swelling.
Home measurement: trace the foot on paper while standing, measure the widest point of the trace (typically across the ball of the foot at the metatarsal heads). Use the measurement chart provided by the shoe brand to determine width letter.
Practical indicators you need wider shoes: you can see the shoe’s upper bulging or distorting at the sides, your pinky toe or bunion hangs over the sole edge, you have pressure corns or calluses on the outer aspects of the toes, or the shoe creates visible indentation marks on the foot after wear.
Conditions Requiring Wide or Extra-Wide Shoes
Bunions: The medial eminence of a bunion extends beyond the standard shoe width. At minimum, a D (wide women’s) or 2E (wide men’s) is needed. Severe bunions may require 4E or specialty footwear. The toe box must accommodate both the bunion and the angled position of the big toe.
Hammertoes: Contracted toes that project upward require additional vertical clearance in the toe box as well as width. Deep toe box shoes (1/2 inch of clearance above longest toe in standing) are specifically designed for this.
Peripheral edema: Fluid accumulation from venous insufficiency, heart failure, or lymphedema changes foot size dramatically during the day. Adjustable footwear (Velcro straps) and extra-wide shoes accommodate this variation.
Diabetic feet: Therapeutic diabetic footwear (Medicare-covered for qualifying patients) is typically available in multiple widths including 4E and 6E, with soft, seamless interiors to prevent pressure ulcers.

Dr. Tom Biernacki’s Recommendation
If I had to give one single piece of footwear advice, it would be this: have your feet measured — length AND width — by a trained shoe fitter, and take the width recommendation seriously. Seventy percent of people wear shoes that are too narrow. That single change — wearing the correct width — resolves or prevents more foot problems than almost any other intervention. New Balance, Brooks, ASICS, and Altra all make excellent wide-width options that don’t look like orthopedic shoes.

Frequently Asked Questions
How do I know if my shoes are too narrow?
Signs: corns on pinky toes, bunion pain, hammertoe irritation, marks from the shoe upper on the toes after wear, inability to wiggle toes freely.
Should both feet be measured for width?
Yes — most people have slightly different-sized feet. Fit to the larger foot and use padding in the smaller shoe if needed.
Do feet get wider with age?
Yes — the natural ligament laxity that increases with age allows the foot to spread. Most adults find they need a wider width shoe by their 50s and 60s than they wore in their 20s.
What is the widest shoe width available?
Specialty brands offer up to 6E or 10E width for severely wide feet. Pedorthists and therapeutic footwear suppliers carry these.
