Translation of "txapin" into English

Ez omen zuen berak oinetako takoidunik, eta etxean txapinekin ibiltzen omen zen beti; zaharra zela etxea, egurrezkoa, hori izango zela. Zapuztuta zegoen: zaratak berdin-berdin entzuten zituen, ez zekien zer egin.

She [the neighbor upstairs] said she didn't have any high heels, and that she always wore slippers in the house; the house was old and made of wood, that must be it. He was frustrated: he could still hear the noise just the same, and he didn't know what to do.
