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.

Heel Height Guidelines

Heel heights are measured on the middle of the heel as shown here. Heel heights are also determined by the size of the shoe. As the shoe gets larger, the heel gets proportionately higher. In other words, the heel on a size 6 will not be as high as a heel on a size 11.
