Our models typically wear US Size 2-4 or Australian Size 6-8, X-Small, Small, or One-Size garments.
On each product page, we provide the model's measurements and what size she is wearing to help guide you.
You can refer to the charts when selecting sizes but please note that sizes cannot be guaranteed and might vary slightly between brands.

The high-vis Michelin© sole for all-terrain traction.

The Bloom® Foam insole is made using the sustainable alternative to synthetic and petrochemical EVA foam, derived from algae biomass. This algae can damage our oceans, so harnessing it in our footwear helps clean up the environment.

Breathable, lightweight and comfortable.

Mesh construction provides efficient drainage and keeps out sediment and debris, while water resistant materials ensure the boot doesn't absorb water, keeping them light and comfortable.

Strong, non-marking rubber compound for sticky grip and high-abrasion when you need it most.

*The main materials in all our Vegan* products are synthetic and aren’t derived from animals. We don’t (yet) have the transparency we need over the production of all the small components (such as adhesives and dyes) used in these products to ensure they meet vegan best practices. So, whilst we believe the shoes are vegan, we’re not yet able to guarantee it and want to be fully transparent.
