Cosy slippers at home

About Mercredy: Mercredy is a Spanish footwear brand we stock for its sustainable slippers. Made in Spain, each pair uses recycled plastic recovered from the ocean, spun into a soft felt fabric and vulcanised to a natural rubber sole. They are fully vegan, lightweight and surprisingly hard-wearing for a house slipper, with a breathable textile insole. If you want cosy feet without the guilt, they are well worth a look.

Mercredy fit & sizing tips

  • Size up if you are between sizes. Mercredy’s own guidance, and what we see with the felt slippers, is to take the larger size when your foot falls between two.
  • A snug felt upper that gives slightly. The recycled felt moulds to your foot with wear, so a neat first fit is normal and they loosen a touch after a few days at home.
  • Flat rubber sole, indoor mainly. The non-slip natural rubber sole is fine for quick trips to the garden or the bins, but we would treat them as house slippers rather than outdoor shoes.
  • Our take. A cosy, eco-minded slipper that feels genuinely different from the usual fluffy mule, and makes a thoughtful gift.

Glossary

Recycled PET felt

A soft fabric woven from plastic bottles recovered from the ocean, used as the upper on Mercredy slippers. Each pair uses two plastic bottles recovered from the ocean.

Vulcanised rubber sole

A natural rubber outsole vulcanised to the felt upper, giving Mercredy slippers their flat, non-slip base.

Frequently Asked Questions

Do Mercredy slippers run true to size?

We find Mercredy slippers true to size for most feet in your usual EU size. If you are between two sizes, take the larger one. That is the note retailers give with the slippers, and it matches what we see.

I’m between sizes. Should I size up in Mercredy?

Yes. The felt upper is fairly forgiving, but sizing up when you are between sizes gives a more comfortable fit from the first wear, especially if you like a sock underneath.

Can I machine wash Mercredy slippers?

No. Mercredy advises against machine washing, as it can damage the recycled felt upper and the vulcanised rubber sole. A gentle brush and spot clean is the safer option if they need freshening up.

Are Mercredy slippers vegan?

Yes. The slippers we stock use a recycled PET felt upper, a breathable textile insole and a natural rubber sole, with no animal products in the construction.

What are Mercredy slippers made from?

Each pair starts with plastic bottles recovered from the ocean, which are processed into a soft felt fabric for the upper. That is vulcanised to a flat natural rubber sole, and the brand holds Global Recycled Standard certification on the recycled content.

Can I wear Mercredy slippers outside?

The non-slip rubber sole will cope with a quick trip to the bins or the garden path, but we would treat them as house slippers rather than outdoor shoes. They are lightweight felt slippers, not hard-wearing outdoor footwear.
