UGG Size Guide — Shoes & Accessories
UGG is a California brand founded in 1978 by Brian Smith in Santa Monica. Initially specialized in sheepskin boots for surfers, UGG has become one of the most iconic footwear brands in the world. Today owned by Deckers Brands, UGG offers boots, slippers, sneakers, sandals, and accessories made from sheepskin and premium materials.

Alpinstore Anti-Return Tips — UGG
- Classic boots (Mini, Short, Tall, Ultra Mini) run large. The UGG rule: go down half a size, or even a full size, from your usual size. The inner fleece flattens with use and the boots slightly stretch.
- Platform slippers (Classic Mini Platform, Ultra Mini Platform, Tazz, Disquette, Funkette) run large. Always go down half a size. The open heel exacerbates slipping if the size is too big.
- Tasman & Neumel: true to size or with slight tightness at the beginning of wear that disappears after breaking in. Take your usual size.
- No socks: UGG is designed to be worn without socks — the sheepskin fleece thermoregulates and naturally adapts to the foot. If you wear socks, consider going up half a size.
- Official UGG H/F conversion: to convert from women's size to men's size, subtract 2 (e.g.: women US9 = men US7). To convert from men to women, add 2.
- Wide foot: UGG does not offer Wide width on most models. If you have a wide forefoot, take your exact size (do not go down) or try in-store.

3. Size Advice by Model
| Model / Range | Size Advice | Explanation |
|---|---|---|
| Classic Mini / Short / Tall | Runs large — go down -0.5 | The fleece flattens with use. If between sizes, take the smaller one. |
| Classic Ultra Mini | Runs large — go down -0.5 | Same behavior as other Classics. Can soften quickly. |
| Classic Mini Platform | Runs large — go down -0.5 to -1 | Multiple returns confirm that a full size too large is common. |
| Ultra Mini Platform | Runs large — go down -0.5 | Higher platform = less structure around the foot, hence the large effect. |
| Tazz / Tazz Platform | Runs large — go down -0.5 | Open heel = foot slipping back is amplified if too large. |
| Tasman / Tasman II | True to size — usual size | Slight tightness at the beginning of wear, normal. Wide foot: take your exact size. |
| Disquette / Funkette | Runs large — go down -0.5 | XXL platform, very high sole. Slipping accentuated if too large. |
| Neumel / Neumel High | True to size — usual size | More structured construction, laces or zip. Usual size recommended. |
| Scuffette / Coquette / Scuff | Runs slightly large — go down -0.5 | Open-back mules/slippers. Keep the size if wide foot. |
| Goldenstar / Lowmel / Sneakers | True to size — usual sneaker size | UGG sneakers fit like market standards (Nike, Adidas). |
| Sandals (Fluff Yeah, Disco) | Runs large — go down -0.5 | Platform sandals with open heel: same logic as mules. |

5. UGG Materials — Understanding the Differences
Sheepskin
Signature UGG material. Natural wool thermoregulates: keeps warm in winter and cool in summer. Flattens with use in 2–3 weeks and molds to the shape of the foot. Do not machine wash.
UGGpure™
Natural wool woven onto a synthetic backing. Offers the comfort of natural fleece with a more structured exterior. Used in more technical models (Tasman, Neumel High). Easier to maintain.
Twin-Face Suede
Sheepskin with both sides used: suede on the outside, wool on the inside. Traditional material for Classics and Tasman. Sensitive to moisture: use a protective spray before first wear.
TREADLITE by UGG™
Lightweight and flexible rubber outsole, present on most models. Offers traction, durability, and lightness. The EVA sole (Classic Mini Platform) is stiffer and higher.
6. UGG Accessories
Socks
UGG offers merino wool and blend socks, sold in packs. Sizes: S/M (EU sizes 36–40) and L/XL (EU 40–46). Ideal for wearing with Classic boots (but increases the tightening effect).
Tip: if you wear thick socks, go up half a size from your usual choice.
Protective Spray & Care
UGG Sheepskin Water & Stain Repellent: waterproofing spray to apply before first use on any suede or nubuck model. Renew regularly (every 2–3 months with heavy use).
UGG Sheepskin Cleaner & Conditioner: specific cleaner and conditioner to restore shine to suede and nourish the leather.
Hats & Scarves
UGG offers hats and scarves made from merino wool or soft acrylic. One size or S/M/L depending on the models. Pom-pom hats and infinity scarves are the most popular.
No specific size guide for textile accessories — most are one size or adjustable.
Gloves & Mittens
Gloves and mittens in double-faced suede or knit, available in S/M/L/XL. Select size based on hand circumference: S = 17–18 cm / M = 19–20 cm / L = 21–22 cm / XL = 23–24 cm.
Between two sizes: prefer the larger for comfort and movement ergonomics.
7. Care for UGG Shoes
Protection Before Wear
Apply UGG Sheepskin Repellent spray on the entire outer surface, 15 cm away. Let dry for 24 hours before first wear. Repeat after each cleaning.
Cleaning in Case of Stain
Moisten the suede with cold water, apply UGG cleaner with a soft brush in circular motions. Rinse with cold water. Stuff with newspaper to maintain shape. Air dry, away from any direct heat source.
To Avoid at All Costs
Washing machine, dryer, hair dryer, radiator, direct sunlight. Total immersion in water. Alcohol or acid-based products. Dry brushing on wet fabric.
8. UGG Size FAQ
Why do UGGs run so large? Is that normal?
Yes, it is intentional. UGG Classic boots are designed to be worn without socks, the sheepskin fleece completely replaces the sock. Therefore, the shoe incorporates this thickness into its sizing. Additionally, the fleece flattens and expands with use — which amplifies the effect of a large shoe over time. Golden rule: at the first fitting, if the toes slightly touch the end of the shoe, it is the right size. After breaking in, the fleece will leave a few millimeters of space.
Tasman or Tazz — which to choose and what size difference?
The Tasman is the classic UGG slipper with a suede band on top, a standard EVA sole, and a flatter profile. It is true to your usual size. The Tazz is a flat version of the Tasman with a distinctive printed fringe border and a very low sole. It runs slightly large — go down half a size. The main difference is aesthetic and sole height, not foot structure.
Are UGGs waterproof?
No by default. The Twin-Face suede of the Classics and Tasman is water-resistant but not waterproof: in light rain or dry snow, they hold up well. In case of immersion or heavy rain, the suede absorbs water and deforms. The UGG Sheepskin Repellent spray significantly improves water resistance. Some models (Classic Weather Mini, Adirondack) have a more waterproof construction with sealed seams.
Can UGGs be worn with socks?
Yes, but UGG recommends wearing its boots without socks for optimal comfort. The natural fleece absorbs moisture, thermoregulates, and remains comfortable directly against the skin. If you wish to wear socks (for hygiene or preference), choose thin socks and go up half a size from your usual choice. Avoid thick socks that compress the foot and increase fleece wear.
