Width & Fit Guide

Medium (M / D)

Our standard width. Fits most feet comfortably and is the default for most Merrell styles.

Standard Fit

Wide (W / 2E)

Extra room in the forefoot and instep. Ideal for wider feet, high arches, or thicker socks.

Wide Fit

Barefoot & Wide Toe

Select styles feature a foot-shaped toe box that lets toes splay naturally for better balance.

Natural Fit

How to Measure Your Feet

Prepare

Stand on a piece of paper with your heel against a wall. Wear the socks you plan to wear with your new footwear.

Mark & Measure

Mark the tip of your longest toe and the back of your heel. Measure the distance between the two marks.

Compare

Match your foot length in inches or centimeters to the chart above. If between sizes, size up.

Check Width

Measure the widest part of your foot. Use the Width & Fit Guide to select the best fit for your foot shape.

Fit Note: Merrell footwear is designed for trail and outdoor performance. Many hiking styles run slightly roomy to accommodate thicker socks and foot swelling during long hikes.

Measure your feet at the end of the day, when they are at their largest. Always measure both feet and use the larger measurement for the best fit.
