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.

Heavy products (bike trainers/large packs/etc.) may take an additional 3-5 business days delivery. Some very heavy products are not available for shipping outside Australia.
Order Changes/Redirects: Please contact us immediately if you wish to cancel or change your order as we are unable to modify or cancel orders after they have been dispatched. If you require any address changes, re-directions or re-deliveries, you will need to organise this directly with the delivery company handling your parcel (listed in your dispatch notification). Please note we strongly advise against redirections as they can add significant delays, and we are unable to pursue claims for parcels lost or delayed once redirected by customers.
Lost Parcels: If you have not received your parcel within the estimated delivery time and you are worried that the parcel is missing or significantly delayed, please contact the courier for an update (contact details are available on the tracking page).

Customs Fees: Shipments sent to countries other than Australia are sold exclusive of GST (Australian VAT) and may be subject to import duties and taxes, which are levied once a shipment reaches your country. Please note we are legally required to declare the full value of the goods (not including shipping charges) on all packages shipped internationally. We cannot inaccurately describe the contents, claim a lower value or mark as a gift. Please do not ask or expect us to do any of the above. For details of Customs charges please consult your own Customs authorities for the latest rates.
Packages which are returned to us as a result of the recipient's refusal to pay import duties and/or taxes are not eligible for a refund; we are only able to issue a store credit less any postage costs and returned parcel fees that we have incurred.
