What are UGG slippers made of?
UGG is the slipper most people search for this time of year. Searches for "ugg slippers" run about twenty times higher than "wool slippers" in the United States right now, according to Google Trends, and "ugg dupes" is climbing with them.
The fleece is real. UGG lists the Women's Cozy as a sheepskin lining on a Sugarcane EVA sole. EVA is a foam plastic, and the sugarcane part means some of it is made from plants instead of oil. It's still EVA.
UGG's polyester is mostly trim: the edge binding, and a braid on the Tasman and Tazz. Five of the six women's slippers at the top of UGG's slipper page sit on EVA. The Scuffette II is the exception, on a molded rubber sole, and it's on our list below.
The same pattern runs through the category. Hommey's sheepskin slipper, sold as "the it slipper of 2026," sits on an EVA sole with a polyurethane heel patch. Overland's own Classic scuff is real shearling over a memory foam midsole. The fluff is natural. The cushion usually isn't.
What makes a slipper non-toxic
A slipper has four parts: the upper, the lining, the footbed and the sole. Three of them touch your skin. The sole doesn't. The bottom of your foot is also the least absorbent skin on your body, taking up about a seventh of what your forearm does in the classic Feldmann and Maibach study. So the layers worth reading closely are the ones your foot sits inside.
What to avoid
- Memory foam footbeds. Memory foam is polyurethane, a plastic foam, and in a slipper it sits directly under your bare foot.
- Faux fur and "plush" linings. Unless the brand names the fiber, these are almost always polyester.
- Fleece and sherpa. Both are names for brushed polyester when the label doesn't say wool.
- "Wool-inspired" or "wool-look." These describe a texture. Only a fiber percentage tells you what it's made of.
What to buy
- Shearling or sheepskin. The side against your foot is wool, still attached to the hide. The hide is tanned, and few brands say how, so look for one that does.
- Felted or boiled wool. It's wool shrunk into a dense cloth that holds a slipper's shape on its own.
- A natural footbed: wool felt, cork or shearling.
- A sole you can name: natural rubber, latex, cork or leather. A synthetic sole matters less than a synthetic footbed, but it still wears down into your floors.
The 6 best cozy slippers without polyester
1. Shearling Wool Clogs
Parachute
100% wool upper · foam sole · $99
A fluffy, closed-toe clog in 100% wool, in four colors, and Parachute calls the clog itself 100% wool. It calls the sole "sturdy foam" and doesn't name it, which costs it a few points, but the sole is the one part that never touches skin.
2. Shearling Moroccan Slipper
Jenni Kayne
Shearling upper and lining · suede outsole · $275
A Moroccan babouche shape in chocolate shearling, made in Turkey. The back folds down so it wears as a slide or up around the heel as a slipper. The splurge on this list.
3. Sutton Shearling-Lined Sheepskin Scuff
Overland
Sheepskin upper · British Merino shearling lining · suede sole · $159
Made in England by a family company that has been making sheepskin footwear since 1937. A backless scuff on a small wedge, with a suede sole and no foam listed anywhere on the page. It runs narrow, so size up.
4. The Everyday Slip-On
East Perry
100% shearling sheepskin · leather and suede sole · $119
The whole slipper is natural shearling sheepskin, curly side out, on a thick leather and suede bottom. If you're between sizes, East Perry says to size down.
5. Molded Sole Low Back
Kyrgies
100% wool felt upper and midsole · vegetable-tanned leather sole · $129
Handmade in Kyrgyzstan from rolled wool felt, with an extra layer of felt sewn into the midsole for cushion. The leather sole is vegetable-tanned with tree extracts, and Kyrgies says so on the page, which most leather soles don't.
6. Scuffette II
UGG
Suede upper · 17mm sheepskin lining and insole · molded rubber sole · $100
If you want the UGG, this is the one. Of the six women's slippers at the top of UGG's slipper page, it's the only one on a rubber sole instead of EVA, with real sheepskin wherever your foot touches. The edge binding is recycled polyester, and UGG doesn't say whether the rubber is natural.
A pair of sheepskin or wool slippers costs about what UGG's Cozy does, and in a few cases less. The difference is underneath, where your foot actually rests.
For the rest of the outfit, the best 100% wool coats for women and quarter-zip sweaters without polyester follow the same rule. For shoes you wear outside, start with plastic-free shoes.
Frequently asked
Shearling scuffs and clogs. Overland's Sutton ($159), East Perry's Everyday Slip-On ($119) and Jenni Kayne's Shearling Moroccan Slipper ($275) have the same plush sheepskin feel, on suede or leather soles instead of EVA foam.
Felted wool clogs and slippers, like Parachute's Shearling Wool Clogs ($99) and Kyrgies' hand-felted Molded Sole Low Back ($129), and shearling slippers with natural soles from smaller makers like Overland and East Perry.
Slippers made of shearling or wool against the foot, on a sole of natural rubber, latex, cork or leather. Skip memory foam footbeds, which are polyurethane, and faux fur or fleece linings, which are usually polyester.
Ones made from natural fibers that breathe, like shearling and felted wool, with no foam under the foot. Wool absorbs up to a third of its weight in moisture vapor, so feet stay drier than in synthetic slippers.
High-quality women's slippers are made of shearling or felted wool on a natural sole. Jenni Kayne's Shearling Moroccan Slipper ($275), Overland's Sutton sheepskin scuff ($159) and Kyrgies' hand-felted Molded Sole Low Back ($129) all skip polyester and memory foam.
For warmth and dryness, yes. The fleece side of sheepskin is wool, which holds moisture vapor away from skin and insulates without trapping sweat. Look for a pair with a sheepskin footbed rather than memory foam.
Overland's Sutton (sheepskin, suede sole), East Perry's Everyday Slip-On (shearling, leather sole), Jenni Kayne's Shearling Moroccan Slipper and Kyrgies' wool felt slippers. None of them lists foam under the foot.
Less than synthetic ones. Wool absorbs moisture vapor into the fiber, and research from the Woolmark Company found wool holds on to less body odor than polyester. Air them out between wears and they rarely need washing.
