Frequently asked questions
How do I measure my foot?
Stand on paper, mark heel to longest toe, and measure the length. Do it in the afternoon when feet are largest, wearing your normal socks.
Why do sizes vary by brand?
There's no single global standard, and lasts (foot molds) differ. Always check the specific brand's chart against your measurement.
