This article considers welfare and the city and the ways in which pedestrian practices combine in the management and production of urban need and vulnerability as manifest in the experience and supervision of urban homelessness. The article combines writings on urban maintenance and repair with recent anthropological work on wayfaring (in which cities seldom figure). Fieldwork undertaken with rough sleepers, welfare workers and city managers in the city of Cardiff , Wales, provides the empirical basis. The main body of the article is organized around three walks through the centre of Cardiff with individuals variously implicated in care, repair and welfare in the city. In closing we assert the importance of a politics of street welfare in city space.
