Dunlop Men's Work Boots Sizing Guide

Use this guide to find your best fit for Dunlop Men's work boots.

Engineered for the most demanding Canadian job sites, Dunlop boots at Wei’s Western Wear are a masterclass in protective industrial footwear. Dunlop’s sizing philosophy revolves around their proprietary Purofort® technology, a high-pressure foamed polyurethane that contains millions of evenly distributed air pockets. This makes top-selling models like the Dunlop Men’s Work Boot Purofort Thermo+ and the Dunlop Men’s Field Pro Thermo+ significantly lighter and more flexible than traditional rubber. Designed to keep feet warm in temperatures as low as -50°C, these boots offer a "Classic Fit" that prioritizes ample space from the ankle to the toe, ensuring all-day comfort for miners, farmers, and oil riggers alike.

A unique fit characteristic of the Dunlop Explorer Purofort CSA Thermo+ is its "Classic Fit" profile, which is intentionally generous to allow for easy on-and-off transitions and the use of thick thermal socks. A common sizing concern for Wei’s customers is that this spacious design can lead to a "runs large" feel; if you are wearing standard-weight socks or are between sizes, we generally recommend sizing down one full size from your typical leather work boot. For those seeking a more locked-in feel, the Dunlop Field Pro utilizes a "Sneaker Fit" last that hugs the heel and midfoot more snugly to eliminate slippage. By matching your foot measurements to our Dunlop size chart, you’ll ensure your CSA-approved footwear provides the ultimate balance of stability and thermal insulation.
