Check the size label inside the shoe tongue, collar, or insole
Measure your foot length from heel to longest toe
Measure both feet and use the larger measurement
Compare your measurement to a shoe size chart
Check the width if the shoe feels tight or loose
Try the shoes on and make sure there is about a thumb’s width of space at the toe
Walk a few steps to test comfort and fit
Use the brand’s size guide, since sizes can vary by manufacturer
Consider the shoe type, since athletic, dress, and boots may fit differently
Recheck sizing later in the day when feet are slightly larger
