This paper considers the importance of walking for many children and young people's everyday lives, experiences and friendships. Drawing upon research with 175 9-to 16-yearolds living in new urban developments in south-east England, we highlight key characteristics of (daily,t aken-for-granted, ostensibly aimless) walking practices, which were of constitutive importance in children and young people'sfriendships, communities and geographies. These practices were characteristically bounded, yet intense and circuitous. They were vivid, vital, loved, playful, social experiences yet also dismissed, with ashrug, as 'just walking'. We argue that 'everyday pedestrian practices' (after Middleton 2010, 2011) like these require critical reflection upon chief social scientific theorisations of walking, particularly the large body of literature on children'sindependent mobility and the rich, multi-disciplinary line of work known as 'new walking studies'. In arguing that these lines of work could be productively interrelated, we propound 'just walking'-particularly the often-unremarked way it matters-as akind of phenomenon which is sometimes done a disservice by chief lines of theory and practice in social and cultural geography.
