Use this guide to find your best fit across Blundstone Men's Footwear.

Note: Blundstone Boots are in Australian Sizes, Which are the same as UK sizes, Canadian/US sizes are different.

Blundstone Men’s Footwear is known for rugged durability, slip-on convenience, and a true-to-size fit designed for work and everyday wear. Blundstone uses AU sizing, which typically runs one size smaller than US men’s sizing. Most customers should order one size down from their usual US shoe size for the best fit. If you’re between sizes or plan to wear thick socks, sizing up may provide added comfort.

Work and winter styles like the Work Boots Black CSA Steel Toe, Winter Thermal All-Terrain Boots, and the CSA Work & Safety Boot in Waxy Rustic Brown offer a secure heel fit with supportive midsoles and durable outsoles. Safety-toe and insulated designs may feel snug at first but are built to soften and mold to your foot over time.

Blundstone boots are designed for all-day wear and minimal break-in. Choosing the correct size ensures comfort, protection, and long-lasting performance, whether you’re on the job site or wearing them casually.
