Tips and measurement

• The length of the shoe is measured from the heel to the end toe tip on the inside of the shoe (excluding lining and inner sole)

• To find the correct size you should measure your foot from the heel to the toe point. Use the Rubber Duck Foot Measurement Tool or follow the instructions below.
• Always add approximately 2% extra (½-1 cm or ¼-½ inches) to be sure your foot fits in the shoe. For children sizes you should also allow for some extra space to grow in.
• Take into consideration whether it is a winter boot with furry lining or a thinly lined summer shoe. For the winter boot the furry lining will take up some space in the shoe – and you might furthermore wear the boot with thick woolen socks. On the contrary, the thin lining in the summer shoe won’t take up any space and you’ll probably wear thin or no sock at all.
• If one foot is longer than the other, choose your size to fit the longer foot. You can pad the smaller foot with a thin insole.
• If between sizes, we recommend you go up ½ size
