Wool slippers

The warmest slippers are undoubtedly made from sheepskin or 100% wool. These materials provide the best insulation and keep your feet warm for a long time.
Why these slippers in particular?
Sheepskin slippers (warmest)
Have an exceptionally high insulation value.
This material provides excellent insulation because the wool fibres contain tiny air pockets that retain heat, while also allowing the material to breathe and wick away moisture.
Wool / felted wool slippers
Slightly less warm than sheepskin, but still very insulating, breathable and temperature-regulating.
Synthetic slippers (least warm)
May seem warm, but they do not wick away moisture well. As a result, your feet become clammy and eventually feel colder.

Additional factors that affect warmth
- Style: a high-top or closed-heel design is warmer.
- Lining thickness: the thicker the wool, the better the insulation.
- Fit: a little extra room creates an insulating layer of air.

The warmest slippers are made from real sheepskin or wool, preferably in a closed or high-top style. This combination provides maximum warmth and comfort.

Wool slippers are warm thanks to the special properties of wool fibres. Wool fibres contain tiny air pockets that retain heat (insulating properties). At the same time, wool is breathable and regulates moisture, keeping your feet warm and dry.

Wool fibres are truly a wonder of nature, with properties that no synthetic material can match. They breathe, regulate heat and therefore always feel comfortable.

If your feet tend to sweat, choose slippers made from breathable, natural materials and avoid synthetic options.
Best choice:
Wool slippers. Wool is breathable and moisture-regulating: it absorbs moisture and gradually wicks it away. Wool keeps your feet at a comfortable temperature without making them too warm.
Merino wool or sheepskin are especially ideal: soft, moisture-regulating and comfortable.

Important to know!
Wool does not prevent your feet from sweating, but it does absorb and wick away moisture quickly, helping your feet feel less clammy.

Wool can absorb up to 30% of its own weight in moisture without feeling clammy. This wicks away sweat, so your feet feel less clammy or cold. With synthetic materials, moisture stays on your skin, leaving your feet feeling clammy and sweaty.

Extra tips
Choose a good fit (not too tight → allows air to circulate). Air your slippers regularly and, if possible, alternate between pairs each day.

Comfort depends on personal preference, fit, and use. Wool slippers mold to the foot and provide lasting comfort. Closed-heel models offer extra support, while slip-ons are easier to put on.

The best type of wool for slippers depends on what matters most to you: warmth, softness, or durability. In general, these are the best options:

Sheepskin (warmest & most luxurious)
- Very high insulation value
- Soft, supple, and comfortable
- Regulates temperature and moisture.
Ideal for cold feet and everyday comfort.

Wool felt (durable & retains its shape)
- Compressed wool, dense and strong
- Good insulation and shape retention
- Slightly less soft, but long-lasting
Ideal for intensive use.

Wool borg (soft & affordable)
- Wool knitted into jersey fabric, soft and flexible.
- Warm and comfortable, with the benefits of wool.
- Less hard-wearing than wool felt or sheepskin
Lightweight, soft slippers at a lower price.

What’s the best choice?

For maximum warmth: sheepskin
For durability: wool felt
For soft, lightweight slippers: wool borg

In short:
There is no single best type of wool. Sheepskin is the warmest, wool felt the strongest, and wool borg a soft, affordable option, though it is slightly less hard-wearing.

Storage: after use, place your slippers in a cool, dry spot, away from direct sunlight or a heater. This helps the wool fibers retain their resilience and keeps your slippers soft and in shape.
Protection:
Before wearing your slippers for the first time, treat them with a protective suede or leather spray (not mousse).
This will help them resist water and dirt. Reapply the spray regularly.

Tip: If you wear your slippers often, the wool under your feet may flatten a little; this is a natural process. Add a sheepskin insole and they’ll feel “like new” again.

Yes, wool slippers are suitable for every season.
Wool regulates temperature. In winter, they retain warmth, while in milder temperatures, they allow ventilation. This makes them comfortable all year round.

For wool felt slippers: wash carefully on a wool cycle at a maximum of 30°C using wool detergent. This is only necessary occasionally, as wool is naturally self-cleaning; airing them out is often enough. Washing is at your own risk.

For sheepskin slippers: do not wash them.
Why sheepskin cannot go in the washing machine:
Sheepskin consists of two parts: wool on the inside and leather on the outside. This combination is what makes it delicate: if the leather gets wet, it can harden and crack. The wool can felt and shrink due to friction. The slipper loses its shape, softness and comfort.

So how should you care for sheepskin slippers? The good news: washing is often not necessary at all. Wool is naturally self-cleaning. Care for wool slippers by airing them out regularly and gently removing dirt. Before wearing them, and regularly thereafter, apply a protective spray to guard the slippers against dirt and moisture.

A good pair of wool slippers costs between €30 and €130 on average. The price depends on the quality of the wool, the craftsmanship and the finish. More expensive slippers often last longer.
