Do Clarks Run Big? Clarks Sizing & Fit Guide

Clarks sizing depends on the style. Most Clarks shoes run true to size — the main exception is the soft moccasin-construction Wallabee, which runs about half a size large, so many people size down. Here is how to choose your size across the Clarks range, including when to order your usual size and when to go down.

Do Clarks run big or small?

Most Clarks run true to size for everyday adults. The main exception is the soft, moccasin-style Wallabee, which runs about half a size large, so if you are between sizes or want a closer fit, order half a size down. The Desert Boot, structured dress shoes, and Oxford styles run true to size.

What size Clarks should I order?

• Wallabee: runs large — order half a size down.
• Desert Boot: true to size — order your usual size (offered in half sizes).
• Dress and Oxford styles (lace-ups, loafers, brogues): true to size — order your usual size.
• Cloudsteppers and cushioned casual styles: true to size, with a slightly more generous toe box — order your usual size.
• Sandals and wedges: true to size.

What if I am between sizes?

For the Wallabee and other soft moccasin styles, size down to the nearest half size — the lightly lined uppers give a little as they break in. For the Desert Boot, structured dress shoes, and Cloudsteppers, stay at your usual size. If you have a wider foot, look for a wide-width option before sizing up.

Does Clarks come in wide widths?

Yes. Wider widths are available on many Clarks styles, especially men's dress and casual shoes. Choosing a wide width is usually better than sizing up for length, because going up a full size makes the heel and instep loose. If you are not sure whether a specific model comes in a wide, call our store team.

How does Clarks sizing compare to other brands?

Clarks fits closer to true-to-size than UGG or Birkenstock. If you wear a US 10 in most brands, you will usually take a 10 in Clarks dress styles and the Desert Boot, and a 9.5 in the Wallabee. Clarks uses a different last for each style, so the per-style guidance above is the most reliable.
