Our reproduction German boots are originally sized in European (metric) sizes so they run a little large. Your best bet is to order your regular size and be sure to use a good insert and socks with the boots. Please see the size chart on each item page for details. Note to customers: Because of the many discrepancies between sizing systems and the differences between manufacturers, it is never a good idea to buy shoes based solely on these conversions. We have listed the measurement of the inside of the shoe heel to toe and list in centimeters and inches, buyers should measure their feet to compare and choose the correct size.
