What size shoes do I need? How do I convert from American to Euro sizes?
As you have discovered, most cycling shoes come in European sizes. To help you get the right shoe, each shoe’s product page has a link to a manufacturer specific size conversion chart. Use your street shoe size to select the correct Euro size from the chart. Do not use your running or athletic shoe because they are generally purchased in bigger sizes to provide more room in the toe box to accommodate the hard stops associated with sport.
