I ordered 11 1/2 and sent 10 1/2 beautiful, functional Chung Shi for a person with much smaller feet than me - accidentally picking and shipping a package is one thing. However, this appears to be an incorrect listing for order creation and inventory reduction - the supplier listed 11 1/2 UK (12 US) and shipped 10 1/2 UK (11 US). My order was called Revain "fishing" email based on my previous searches, this trick will never work again.
