The Bill Ringa Fold Rotterdam is handmade in Portugal from 100% natural lambswool felt that moulds to your feet for a natural fit, keeping them dry, warm and comfortable. Its adaptable heel lets you choose between a relaxed slip-on or a more secure fit, while the sturdy sneaker sole makes these wool house shoes just as reliable outdoors as indoors.
 
Updated in 2022 with refinements to the instep and linework, the Fold Rotterdam now carries a sleeker, more contemporary profile.
 

Colours

The grey mélange of natural lambswool, left entirely undyed, pairs effortlessly with the white sole for a clean, refined look. Grey has long been one of the most popular choices for Bill Ringa wool house shoes, valued for its neutral versatility that complements almost any outfit. Owing to high demand, the white sole has now been reintroduced, giving this timeless shade a fresh and striking balance of colour and comfort.
 

Rotterdam

Rotterdam. Built on concrete and steel, shaped by the harbour and carried by people who call it as they see it. No frills, just raw simplicity and strength. The Fold Rotterdam captures that spirit: a grey upper reflecting the city’s grit, grounded on a white sole that stands for clarity and new beginnings. A combination as honest and uncompromising as Rotterdam itself — bold, functional, and effortlessly comfortable.
