We use AUS/NZ size metric for both men and women. The best way to determine the size of your boots is by referring to the current boots or footwear you are wearing, and use the conversion chart below to place an order. Of course, the current boots that you are wearing must be comfortable and of the right size before conversion. All our boots are already in a 2E wider fitting. If you need an even wider width, please choose a half size bigger to cater for that.
