When I lived in E1/2/3, variously, and worked in EC, variously, for about 15 years I always happily teetered around in heels cos it took about 20 mins to easily get home, or less in a cab obvs. But once I moved out t’country, nope, no way, not happening. A two+ hour journey via multiple trains, planes and automobiles meant I fully embraced not just flats but ‘comfy trainers. Yeah, I bet all them in heels ARE locals.
