The Bill Ringa Ease Mono Ulaanbaatar carries that natural spirit into a premium wool house shoe. Handmade in Portugal from 100% lambswool felt in earthy mélange brown — one of the fleece’s own shades — it’s built for contrasts, much like the Mongolian climate: soft and warm in icy winters, light and breathable in summer heat. These felt slippers mould naturally to your feet, offering dependable ease every day.
In 2022 the heel stitching and instep elastic were reworked for a sharper profile and more refined finish — footwear designed to endure every season with style.
This brown mélange is one of the sheep’s natural fleece colours — entirely undyed, just as nature intended. The result is a beautifully nuanced tone that pairs effortlessly with any skin tone and complements every outfit. Combined with the light gum sole, it gives the house shoe a refined, flattering finish.
Named after Mongolia’s capital, surrounded by vast steppes and rugged mountains, Ulaanbaatar evokes a landscape of earthy tones and quiet strength. The brown mélange wool reflects that spirit — grounded, resilient, and full of depth. Paired with its light sole, the Ease Mono Ulaanbaatar carries the calm endurance of the steppe into the comfort of your home.

With wool’s natural ability to repel water and dirt, these felted wool shoes remain resilient even in light rain. Keeping them in good condition is straightforward: wipe with a damp cloth or hand-wash in cold water using a delicate wool detergent.
The Bill Ringa sole, made from durable rubber, is designed to resist dirt as well — easy to clean with a single wipe, so your indoor-outdoor slippers stay fresh with very little effort.
