How to read a shoe size chart

Start with the unit

Stand in the socks you expect to wear. With your heel against a wall, mark the end of your longest toe on a sheet of paper. Measure from the wall to the mark and repeat on the other foot. Keep the larger measurement handy.

Read the column heading

A US size, a UK size and a length in centimeters describe different things. Use the chart on the specific product page and check whether it lists foot length or insole length before comparing it with your measurement.

Check the exchange details

If your measurement falls between sizes, ask the retailer about that model. Read the return window, the condition required for a return and who pays return postage before placing the order.
