👟 Shoe Fit Guide
Measuring Your Foot
Stand on paper, mark heel and longest toe, then measure between marks. Do this at the end of the day when feet are largest.
Ideal Fit
There should be about 1cm (thumb's width) of space between your longest toe and the shoe's end when standing.
When to Measure
Feet swell during the day and with activity. For best results, measure in the afternoon or after exercise.
Sock Consideration
Measure with the socks you'll wear with the shoes. Athletic socks add 0.5-1cm to your foot length.
Shoe Types
Running shoes often need more toe room than dress shoes. Consider the shoe type when selecting size.
Regular Checks
Adult feet can change size over time. Measure annually, especially after weight changes or pregnancy.
