Barefoot Benefits
Barefoot Benefits
Wide Toe Box
A wide toe box allows the toes to splay and move naturally, contributing to increased stability and balance.
Zero Drop
Flat zero 'heel-to-toe' drop shoes promote a more natural alignment of the body inducing better posture.
Thin & Flexible Sole
A thin and flexible sole allow for better sensitivity and improve proprioception while strengthening the intrinsic foot muscles.
Care Instructions
Care Instructions
We recommend that you use a ‘protective spray’ on our shoes. Using a horse hair brush to remove any dirt will keep your shoes clean for everyday use, however, stubborn stains may need treatment with a 'suede shampoo' or a 'leather shampoo'.

Our shoes tend to fit on the smaller side, so consider sizing up for a more comfortable experience. Made in full sizes, so if you are in between sizes, we recommend going up to the nearest whole size.
Choose a Size Based on Our Size Guide
We recommend measuring your feet and selecting a size based on this. Make sure you do this during or at the end of the day to ensure the right size (feet typically swell during the day).
-
Wearing socks, stand on a piece of paper with your feet against the wall. Make a mark at the front of your big toe.
-
Now measure between the base of the paper to the marked line. It is important to measure both feet, as one may be longer than the other.
- Determine the longest measurement and add 1.0 to 1.5 cm to that measurement, depending on your preference for extra space. Select a size from our size chart:
