For men, sizing is true to UK standards for a formal shoe. If you have another pair of desert boots, go by that size.

For women, our unisex sizing may differ slightly so please follow the guide below and choose based on the suggested foot length.

Our desert boots are a standard G width fitting.

To measure your feet, place a sheet of paper on the ground against a wall, stand on it with your heel against the same wall, and mark with a pencil around your longest toe (not always your big toe). Make sure the pencil is vertical and wear the same socks that you intend to wear with your boots. For best results ask someone else to do this while you stand still.

Choose the UK size based on the closest 'suggested foot length' in the chart below. Our recomendation allows for 1.5cm room in your boots but if you like your shoes to be tight, then add 1.2cm to your actual foot length and go by that 'shoe inside length'.

If you have any questions at all, please email us on info@billytannery.co.uk before you place an order.
