The practice of climbing by people with disabilities is part of a double societal dynamic, which is affected by a movement of massification, indoorization and commercialization of climbing, but also by the consequences of the law of February 2005 which aims to produce appropriate spaces and services to guarantee the needs of disabled people. This study, which is the result of a field survey conducted as part of an ethno-sociological approach in the Lyon area, describes the deployment of an ongoing process of social innovation, the evolution of which is gradually shifting from a service that is not very or not at all marketable, located in the specialized environment, to more marketable services, located in shared spaces. It highlights a network of socio-technical actors who cohabit, linking or excluding each other according to its orientations and its progressive diffusion. From the case of climbing, this article reveals the complexity of the factors influencing sports consumption and the agencements that make them possible. It highlights the role of non-human actors but also intermediaries human actors who, by bringing people together, maintaining and constantly readapting the bridges created between worlds, make it possible to envisage the perpetuation of access to the consumption of these new services.
