How Do I Find My Size?

We have many brand name shoes in sizes 4-18 and in widths from AA (2A) to EEEEEE (6E).

• If you are familiar with the brand, order the size you would usually buy.
• To shop by your size and width, use our style finder.

Men's Shoe Length Equivalents

Length to order. Please note: European sizing may vary. Refer to the product information on the product page for specific conversions for each shoe.

Men's Widths

Men's Shoe Width Guidelines

• D width is a medium (M) width; this is the regular or average width.
• C width or a B width is a narrow width. If you go down a letter, the width is decreased by ¼ inch.
• E width is a wide width. Every time another "E" is added (i.e. EE to EEE), the width is increased by ¼ inch.

How Do I Measure My Foot?

Be sure to measure both feet and fit to the larger foot.

To measure the length: Measure the foot from the heel to the tip of the longest toe, using a ruler or a tape measure.

To measure the width: Use a tape measure to wrap your foot at the largest part of the foot, so it fits comfortably without any gaps.

Other Fit Tips

1. If you need a ½ size, and one is not offered, order the next size up (i.e. need 9 ½, order 10).
2. If you need a narrow width and a narrow is not available, you may want to order one ½ size down.
3. If you need a wide width and a wide is not available, you may want to order ½ size up.
4. If one foot is larger than the other, order for the larger foot.
5. For women ordering men's sized shoes order 1 ½ sizes down (i.e. women's size 9 = men's size 7 ½).
6. For men ordering women's sized shoes order 1 ½ sizes up (men's size 8 = women's size 9 ½).
7. Some manufacturers only offer their shoes in European or UK sizes. Here, we help you by translating foreign sizes into American, with a sizing chart for that style.
8. If a style is not running true to size, we will provide a fit recommendation.
