Cold mornings shouldn’t mean stiff feet and an outfit you don’t feel good in!
Slip into boots that feel soft, warm, and instantly make your legs look longer and sleeker, without fighting with laces or awkward tight shafts.
Zip-on comfort
A side zipper and stretchy inner lining make these boots easy to pull on and comfortable from the first step. You get a snug fit that moves with your foot instead of rubbing or pinching.
Warmth that follows you
The over-the-knee cut wraps more of your leg, helping you stay warmer when the wind hits. It’s the kind of cozy coverage that makes winter walks feel doable again.
Sleek legs, instantly
That taller silhouette doesn’t just look stylish, it visually elongates your legs and creates a slimmer line. Pair them with a dress, a long sweater, or skinny jeans and watch your whole outfit look more put-together.
Steady steps all-day
A durable TPR rubber outsole grips the ground better, while the soft latex midsole cushions each step. You’ll feel more stable and less tired after long days on your feet.
Lift without the ache
The 5 cm heel gives you a flattering boost without the “why did I do this” feeling after an hour. It’s just enough height to elevate your look while still feeling walkable.
These over-the-knee boots are made for the season when you want warmth, comfort, and a clean, confident silhouette, at the same time. Soft on the inside, sturdy underfoot, and easy to style with everything from a little black dress to your chunkiest knit.
We choose natural, hard-wearing fibers — wool, cashmere, cotton and suede — so each piece looks better with every season. The exact composition is listed in the description above.
Knitwear: hand wash cold or dry clean, lay flat to dry, store folded.
Coats & jackets: dry clean only; brush wool gently after wear and hang on a wide hanger.
Suede & leather: protect with a water-repellent spray and brush with a suede brush.
