Sax reframes the walking interview as a research practice in which place, movement and researcher embodiment actively shape the production of evidence. The central insight is that context is not a background variable surrounding an interview but part of the interview’s epistemic machinery: meanings emerge through movement, sensory attention, memory, hesitation, environmental cues and the evolving relation between participant and researcher. The paper is particularly valuable for its reflexive treatment of uncertainty. Rather than presenting walking as an automatically richer method, Sax examines the instability of insider and outsider positions, the difficulty of separating observation from attachment, and the challenge of translating embodied encounters into conventional academic outputs. Audio, photographs and field notes each retain different fragments of the event, while the lived intensity of being there remains partly irreducible. The contribution bridges place-based qualitative research, participatory action research and environmental justice by treating the researcher’s sensory and affective capacities as disciplined instruments rather than methodological noise.
