Split size shoes for two different size feet — custom made-to-order by Adelante

Is It Normal to Have Feet With Two Different Sizes?

If you've ever noticed that one shoe feels tight while the other feels fine, you're not imagining it — and you're not alone. Approximately 60% of adults have one foot that's longer or wider than the other. For most people the difference is minor: a half size or a slight width variation. For others it's significant enough that standard shoe shopping becomes a genuine problem.

This post covers why feet are different sizes, what your options are, and — critically — where you can actually buy shoes that fit both feet properly.

Why Are Feet Two Different Sizes?

Foot size asymmetry is the norm, not the exception. There are several reasons it develops:

Dominant-side development. Most people favor one side of their body. The dominant foot (typically the right) tends to carry slightly more load over a lifetime, which can cause it to spread or develop differently.
Injury and surgery. A broken bone, ligament injury, or surgical correction in one foot can change how it heals and how weight is distributed across it, affecting long-term shape and size.
Flat feet or high arches. A foot with a collapsed arch spreads wider and longer under weight than an arched foot. If one foot has different arch structure than the other, you'll measure differently in each.
Medical conditions. Conditions like lymphedema, venous insufficiency, or hemihypertrophy (where one side of the body develops larger than the other from birth) can cause persistent, significant size differences.
Aging and pregnancy. Ligaments loosen over time — and especially during pregnancy — causing feet to both lengthen and widen. The process doesn't always happen equally in both feet.

The size difference between feet is rarely dramatic. Most people are within half a size in length. Width differences, however, can be more pronounced: it's common to need a different width in each foot even when the length is identical.

What Are Your Options?

The right solution depends on how significant the difference is.

Option 1: Adjustable Shoes (for minor differences)

If the gap between your feet is small — a half size or less in length, or a single width grade — adjustable shoes can help. Styles with buckles, laces, Velcro, or elastic straps let you tighten one shoe differently than the other to account for the variation. Sandals with adjustable straps are the most forgiving option in this category.

Option 2: Insoles (for half-size length differences)

If you buy to fit your larger foot, a cushioned insole in the larger shoe can take up excess length and improve fit for the smaller foot. This works when the length difference is modest (a half size), but fails for width differences — an insole doesn't change how wide a shoe is.

Option 3: Buy Two Different Sizes (for larger differences)

If your feet differ by a full size or more in length, or by a full width grade, the only real solution is to buy shoes in two different sizes — one for each foot. This used to mean buying two full pairs and discarding the unneeded shoes. Today, a small number of brands offer what's called split sizing: the ability to order a different size or width for each shoe within a single pair.

Where to Buy Split Size Shoes

Split sizing is rare. Most major footwear retailers don't offer it at all. Here's the realistic landscape:

Nordstrom maintains a "split size" program on select styles through their customer service team, but it applies to a limited number of styles and typically requires a phone call or in-store visit.
Some specialty orthopedic retailers offer split pairs, but selection is limited to therapeutic or clinical styles rather than everyday footwear.
Adelante Made-To-Order builds every shoe to order, which means split sizing is a built-in option on every style — not an exception you have to negotiate. You choose your left foot size and width independently from your right at checkout using the Custom Design button on any product page. No upcharge. Men's sizes 4–17, widths C–EEEEE. Women's sizes 4–15, widths A–EEE.

If you need a split size pair, Adelante is one of the few places where it's a standard checkout option rather than a special request.

Frequently Asked Questions

Is it normal for one foot to be bigger than the other?

Yes. Around 60% of adults have feet that are measurably different in size. The difference is usually small (a half size in length or a minor width variation), but for some people it's large enough to make standard shoe shopping genuinely difficult.

Which foot is bigger, left or right?

There's no universal rule. Among right-handed people, the left foot is slightly larger more often than not — but this varies widely. The only reliable way to know is to measure both feet.

What should I do if one foot is bigger than the other?

For a small difference (half size or less), adjustable shoes or insoles may be enough. For a larger difference, the best option is to buy shoes in split sizes — a different size for each foot. Adelante offers split sizing at no extra charge across all styles.

Can you buy two different size shoes?

At most retailers, no. Split sizing — ordering a left shoe in one size and a right shoe in a different size — is not widely offered. Adelante Made-To-Order is one of the few brands that includes it as a standard option at checkout on every style.

One foot is wider than the other. What are my options?

Width differences are just as common as length differences, and just as underserved by mass-market footwear. Adelante's width spectrum runs from narrow (C for men, A for women) to extra wide (EEEEE for men, EEE for women), and you can choose a different width for each shoe in a split-size order.
