The Right Shoe Project
Shoes are made in many factories around the world and even models within the same brand can be quite different. To assist our customers in choosing the right size, we measure every shoe we receive. All this information is compiled so you can simply enter the length of your foot in centimetres, choose your preferred fit, and our calculator will recommend a size for you! Then, as you browse the website across various brands and models of shoes, we will provide a recommendation of your sizing in each model.
Still not sure? If you're in Brisbane, feel free to come in to our store in Milton for a fitting. Otherwise, you can contact our team for assistance and advice. If you would like to contribute to helping other customers please contact us with your shoe size, foot length and how well your shoes fit.
