The Bill Ringa Fold Cairo is a wool house shoe in natural brown, handmade in Portugal from undyed lambswool felt — one of the fleece’s original shades. A modern take on the classic slipper, it features a fold-down heel you can step on and a flexible sole that makes it suitable for outdoor wear. Soft, warm and breathable, these felted wool slippers mould naturally to your feet for year-round comfort. Kept straightforward and practical, the Fold’s pull tab and collapsible heel make stepping in and out effortless.
Updated in 2022 with cleaner lines and refined instep stitching, the Fold Cairo now presents a timeless yet more contemporary silhouette.
Paired with the light gum sole, this brown mélange wool creates a refined and flattering finish. Taken straight from the sheep’s natural fleece, the shade is left completely undyed, just as nature intended. The result is a subtle, nuanced tone that works with every outfit and complements any skin tone.
Named after Cairo, the ancient city watched over by the pyramids of Giza. From the summit, the view stretches endlessly — desert sands, stone horizons, and the timeless line of the Nile. The Fold Cairo recalls those natural tones: a mélange brown upper, the pure colour of wool in its raw state. Honest, grounded, and enduring — a shade that carries the stillness of stone and the warmth of the earth into the ease of home.

Naturally resistant to water and dirt, wool felt makes these house shoes ideal for both indoor comfort and occasional outdoor wear. To keep them fresh, simply wipe with a damp cloth or hand-wash in cold water with a gentle detergent.
Our Bill Ringa rubber sole is built to resist dirt too — after outdoor use, a single wipe restores them to their best.
Our slippers are manufactured by Perfect Eject, based in Felgueiras — the heart of Portuguese shoemaking. Here, craftsmanship is passed down like a family heirloom. Skilled men and women cut, stitch, and press with care, blending tradition with modern expertise to create wool footwear that offers not only comfort and durability, but also the spirit of the people who make them.
