The Bill Ringa Chelsea F Baku is a wool house shoe in elegant black, handmade in Portugal from 100% natural lambswool felt. Its refined Chelsea-inspired silhouette combines clean lines with everyday wearability, offering warmth, softness and breathable comfort throughout the year. The felt naturally moulds to the shape of your feet, creating a personalised fit that only improves with time. Durable yet lightweight, it is as suited for quiet moments indoors as it is for quick steps outdoors — a timeless design crafted with care to keep you at ease, wherever you go.
Black felt meets the light gum sole in a contrast that feels both classic and contemporary.
The combination adds warmth to the depth of black, softening its edge without losing its elegance.
Refined, adaptable and quietly bold — a colourway that pairs effortlessly with everything.
A name shaped by contrast. Where the Black Sea meets desert winds, and firelight dances on ancient stone. This deep black tone echoes that same allure — strong yet fluid, mysterious yet refined. A shade that feels powerful in its calm, timeless in its elegance.
