Quick answer: UGG has made several over-the-knee styles, including the New Heights Platform Xtra Over The Knee Boot. Nordstrom currently marks that model sold out. Its Sacai collaboration includes a thigh-high boot listed at US$1,000 at Nordstrom. For the classic sheepskin look in a tall height, the new Classic Ultra Tall ($295) reaches the knee. The Classic Tall II sits just below it. Older favourites like the Bailey Button Over the Knee and Loma Over the Knee now mostly appear on resale sites.
A tall sheepskin boot keeps your legs warm under a skirt, dress or leggings, and feels like a slipper inside. The tricky part is that UGG changes its tall-boot line-up often. Many “best over the knee UGG” lists still recommend discontinued boots, or ones that stop below the knee.
Below, documented models are kept separate from confirmed stock. You’ll also see how tall, knee-high and over-the-knee differ, plus styling and care tips.

How over the knee, knee-high and tall boots differ
| Style | Where it ends | Example |
|---|---|---|
| Tall / mid-calf | Below the knee, around the upper calf | UGG Classic Tall II |
| Knee-high | At or just below the knee | UGG Classic Ultra Tall |
| Over the knee (OTK) | Above the kneecap, on the lower thigh | UGG New Heights Platform Xtra Over The Knee |
| Thigh-high | Mid to upper thigh | UGG x Sacai Thigh High Boot |
Where a boot ends on your leg depends on your height and leg length. Before ordering, compare the shaft height against your own leg. Shaft height is measured from the insole or arch to the top of the boot.
The Best Over the Knee and Tall UGG Boots
1. UGG New Heights Platform Xtra Over The Knee Boot
Best for: a true over-the-knee UGG with extra height.
UGG lists the New Heights Platform Xtra with a 19.5-inch shaft, 3.2-inch platform and 4.5-inch heel. Nordstrom’s listing is sold out, so check local stock rather than treating it as an available recommendation. A platform does not make a boot waterproof or safe on ice. Wear it with a short skirt or dress and a longline coat, or tuck in slim leggings.
- Pros: genuine over-the-knee height, platform adds height; traction depends on the surface.
- Cons: platforms take some getting used to; bulkier than a classic flat sole.
2. UGG x Sacai Thigh High Boot
Best for: anyone who wants a bold fashion statement.
UGG’s collaboration with the Japanese label Sacai takes the familiar sheepskin boot all the way up the thigh. It’s a runway piece with a runway price, listed at $1,000 at Nordstrom. Choose it if you want the most dramatic version of the look.
- Pros: unique, designer collaboration, maximum leg coverage.
- Cons: very expensive; limited sizes and stock.
3. UGG Classic Ultra Tall Boot
Best for: the classic UGG look at its tallest.
Released in autumn 2026, the Classic Ultra Tall stretches the iconic Classic boot’s shaft up to the knee. It comes in chestnut, black and dusted cocoa for $295. On most people it won’t go over the knee. Don’t confuse it with the separately named Classic Ultra Ultra Tall, which UGG lists with a 26-inch convertible shaft.
- Pros: instantly recognisable, cosy, easy to wear.
- Cons: knee-high rather than over the knee for most heights.
4. UGG Classic Tall II
Best for: an everyday tall boot.
The Classic Tall II is a long-running favourite with twin-face sheepskin and a lightweight sole. Its shaft ends below the knee. You can fold the top down for a slouchier look. It’s a good choice if you want warmth and versatility more than over-the-knee height.
5. Older Styles and Resale Listings
If you love a specific older style, resale sites like eBay and Poshmark are where to look. Older names you may encounter include:
- Bailey Button Over the Knee, a sheepskin boot with the signature wooden button.
- Loma Over the Knee, a sleeker suede boot with a side zip.
- Classic Mondri Over the Knee, a tall suede boot with a wedge.
Buy from sellers with good ratings, and check photos of the soles and inside lining. Look for authenticity details like the UGG heel label and the security label inside newer pairs.
Check the brand: this guide discusses UGG-branded products. Similar-looking sheepskin boots from other makers can have different materials, sizing and care instructions.
How to pick the right height and fit
- Measure your leg. Compare the shaft height with the distance from your arch to just above your knee.
- Check the calf and thigh width. Over-the-knee boots should be snug enough to stay up, but not so tight that they pinch when you sit.
- Size for sheepskin. Sheepskin lining compresses and moulds to your foot over time. UGG generally suggests a snug fit in its classic boots. Don’t automatically size down, though, as fit advice varies by style. Check the size guide for the specific style.
- Think about weather. Suede isn’t waterproof. Treat it with a protector spray, or choose a wet-weather style if you live somewhere rainy or snowy.
How to Style Over the Knee UGG Boots
- Sweater dress + boots: the classic look is a chunky knit dress that ends mid-thigh. A few inches of leg or tights show above the boot.
- Mini skirt + tights + long coat: black tights, a mini skirt and a camel or charcoal coat that falls past the boot top.
- Leggings + oversized knit: slim leggings tucked in, with a long jumper or shirt that covers your hips.
- Skinny or slim jeans: tucked in, with a fitted top and a cropped puffer or shearling jacket.
- Keep the colours tonal. Chestnut boots look great with cream, camel and brown; black boots with grey, black and burgundy.
- Balance the volume. Tall, chunky boots look best with a more fitted top half, or a long coat that creates one long line.

How to Care for UGG and Sheepskin Boots
- Protect before you wear. Spray new boots with a suede and sheepskin protector, following the spray’s compatibility, drying and reapplication instructions.
- Brush regularly. Use a soft suede brush to lift the nap and remove dry dirt, always brushing in one direction.
- Dab, don’t rub, wet spots. Blot with a clean cloth and let the boots dry naturally.
- Dry at room temperature. Stuff them with paper to hold their shape. Keep them away from radiators, heaters and direct sun, which can shrink and harden sheepskin.
- Remove salt stains quickly using a cleaner made for sheepskin or suede.
- Don’t machine wash unless the product label specifically says you can.
- Store upright with boot shapers so tall shafts don’t crease or flop over.
Questions people ask about tall UGG boots
Does UGG make over the knee boots?
Yes, documented styles include the New Heights Platform Xtra and the Sacai Thigh High Boot. Availability varies; the New Heights listing checked at Nordstrom was sold out. Check the specific model, size and region before ordering.
Is the UGG Classic Tall over the knee?
No, the Classic Tall II ends below the knee. The newer Classic Ultra Tall reaches about knee height. Neither is designed to go over the knee on most people.
Should you wear socks with UGG boots?
UGG’s sheepskin lining is designed to be worn barefoot, as it wicks moisture and helps regulate temperature. Many people still wear thin socks for hygiene. Either way works; just avoid thick socks that make the fit too tight.
Are over the knee UGG boots waterproof?
Most suede and sheepskin styles are not waterproof. Some have water-resistant treatments, but you should still use a protector spray and avoid deep snow and heavy rain.
How do I keep over the knee boots from slipping down?
Choose a pair that’s snug at the thigh. Try suitable leggings or tights and check the shaft fit while sitting and walking. Avoid adhesives that could damage the lining.
How long do UGG boots last?
With regular brushing, protector spray and proper drying, a good pair can last several winters. Daily wear in wet weather will shorten their life.
Check fit and stock before ordering
For a true over-the-knee fit, compare shaft heights and sizes on the New Heights Platform Xtra or Sacai boot. If you want everyday warmth and the classic UGG feel, the Classic Ultra Tall or Classic Tall II is easier. Both still look great with dresses and leggings. Whatever you choose, protect the suede from day one and your boots will look good for years.
