Because people in different countries have different shoe size,and our company is EUR size and foot length (marked on the shoe size lable) as the standard.
Please make sure and choose size by your foot length!
So you only need to accurately measure feet,and then refer to the size chart to choose the correct size.
1) The size you select is US size ,not UK size.
2)If your foot is fat and wide, we suggest you choose one size larger!
3)If you don/'t know how to select ,tell us your foot length.
