Warm, weatherproof and winter-ready

Tasmania doesn't do mild winters. The island that made Blundstone is the kind of place where the weather comes in fast and stays for a week, and it's that heritage that sits behind the Thermal Series. The #566 is built around a weatherproof full grain leather upper with latexed seams and coated, water-repellent elastic side panels: in other words, no weak points. Inside, Thermal Thinsulate insulation does the work that thick, heavy linings used to do, without the bulk – and a removable sheepswool footbed takes care of the cold coming up from the ground. Cushioned heel technology absorbs the repetitive impact of a full day outside, and the TPU outsole handles whatever you're standing on. Pull tabs, elastic sides, lace-free: it's still a Blundy, through and through. This is the boot to reach for when the forecast is grim but you've going out there anyway.

Born in colonial Tasmania in 1870, Blundstone is one of the world's most enduring boot brands – and one of the most no-bull. Founded by John and Eliza Blundstone in Hobart, the brand started making fit-for-purpose footwear for the hard yakka of island life: cobbled city streets, farmland, factory floors. The iconic elastic-sided Chelsea silhouette arrived in the 1960s, and the original pattern has barely changed since. There's a reason for that.

Over 150 years, Blundstone has remained committed to a simple philosophy: make boots that work. Tough enough for a day's hard yakka, comfortable enough to pull on for the commute or a night out, understated enough to never look out of place.

The Originals Series stays true to that founding blueprint – single-piece leather construction, unlined for breathability, with cushioned heel technology and a hard-wearing outsole. The Classics Series builds on the Original with a roomier fit, leather lining, and the SPS Max Comfort system for long days on your feet. Clogs bring the same no-nonsense ethos to a slip-on silhouette, with memory foam footbeds and that unmistakable Blundies build quality.

On sustainability, Blundstone maximises recycled and recyclable materials in manufacturing, uses 100% recyclable single-material packaging, and minimises fossil fuel use across its supply chain. Boots built to last – in every sense.
