Foot Length to Shoe Size Converter

Direct Answer Summary

To convert measured foot length to your correct shoe size, measure the distance from your heel to longest toe in centimeters and add 1.5 cm of clearance allowance. For example, a 26.5 cm foot length needs a 28 cm internal shoe last, corresponding accurately to a US Men's size 10.

Convert measured foot length in inches or centimeters directly to your exact US, UK, and European shoe size with toe allowance calculation.

Common Questions

Frequently Asked Questions.

Expert answers regarding footwear fit, regional size variations, and measurements.

Why do I need to add extra clearance to my foot measurement?↓

Your foot lengthens during movement as your arch flexes. A clearance of 10 to 15 mm prevents repetitive toe trauma.

What shoe size is a 10.5 inch foot?↓

A 10.5 inch (26.7 cm) foot corresponds to a US Men's size 9.5 or Women's 11 (EU 43).

Should I measure both feet?↓

Yes, most people have one foot slightly larger than the other. Always choose your shoe size to fit the larger foot.
