Koolaburra

Yes. Koolaburra and UGG share a parent: Deckers Brands acquired Koolaburra in 2015 and positioned it under its UGG brand. So while Koolaburra is not the UGG line itself, it sits inside the same family, which is why people often think of it as UGG's more affordable sister label. The two are related by ownership, not identical in product.

The headline difference is the upper. UGG boots are built around a sheepskin upper with a wool inner lining and a tanned outer surface, which is the premium material UGG is famous for. Koolaburra is positioned as the more accessible option under the same parent, so buyers generally weigh a lower price against UGG's signature sheepskin warmth and feel. If maximum plushness and cold-weather warmth are your priority, that is UGG's territory.

For casual, milder-weather wear, many owners find Koolaburra a genuinely comfortable, good-value pick that scratches the cozy-boot itch without the flagship UGG price. The trade-off is that the more affordable build is generally not engineered for the same lifespan or extreme-cold insulation as premium sheepskin. Treat them as easygoing everyday boots rather than a decades-long investment piece.

It comes down to how and where you will wear them. If you want a stylish, budget-friendly boot for around-town wear in moderate winters, Koolaburra makes sense. If you need maximum warmth, the true sheepskin feel and the longest service life for harsh climates, UGG's flagship sheepskin still holds the edge and may justify the higher spend.

Deckers Brands, the American footwear company behind UGG, acquired Koolaburra in 2015 and positioned it under its UGG brand. That placement lets the family reach shoppers who want the cozy sheepskin-style look at a more accessible price than the flagship line. In effect, Koolaburra extends the group's range downward in price while UGG anchors the premium end.

Koolaburra is owned by Deckers Brands, formally Deckers Outdoor Corporation, an American footwear designer and distributor founded in 1973 and based in Goleta, California. The same company owns UGG, Teva and Hoka. Koolaburra joined that portfolio when Deckers acquired it in 2015.

Deckers Brands has a broad footwear portfolio beyond Koolaburra and UGG. It also owns Teva, the sports-sandal pioneer it has distributed since the mid-1980s, and Hoka, the running-shoe brand known for its oversized, maximalist midsoles, which Deckers acquired in 2013. The group's roots go back to flip-flops and leather sandals sold along the US West Coast in the 1970s.

UGG boots gained wide recognition after they were included in The Oprah Winfrey Show's Favorite Things segment in 2003. Surfing had already helped carry the sheepskin boot beyond Australia and New Zealand, after surfer Brian Smith began selling them in the US in 1979. That cultural momentum is the backdrop against which Koolaburra was later positioned as an accessible sister label.

They are better suited to mild and indoor-outdoor wear than to extreme cold. UGG's draw is its sheepskin-and-wool construction that traps warmth, and Koolaburra sits below that as the value option, so it is generally lighter on insulation. For deep winter or long stretches outdoors in freezing temperatures, plan accordingly or choose a more heavily insulated boot.

Koolaburra has typically been sold through mainstream footwear and department retailers as well as online marketplaces, in keeping with its accessible, value-focused positioning. Buying from established retailers is the safest way to be confident in sizing and authenticity. Because it sits under the UGG umbrella at Deckers, you will often find it alongside other cozy-boot options.

Treat them like any soft, cozy boot: keep them out of soaking conditions, let them dry naturally away from direct heat, and brush the surface gently to lift the nap. Avoiding heavy rain and salt will extend their life, since the value-tier build is less rugged than premium sheepskin. A protective spray suited to the material adds a useful first line of defence.
