脱ぐ ('take off') and 履く ('put on, wear') are the verb pair specifically for footwear — and for anything you put on the lower body, like trousers, skirts, or stockings. Japanese splits the English 'wear' across multiple verbs: 着る for tops and dresses, 履く for the lower body and shoes, かぶる for hats and headgear, つける or する for accessories. Removing shoes when stepping inside is a deeply ingrained custom — the 玄関 (entryway) of every Japanese home, and many traditional inns, restaurants, and temples, marks the line where shoes come off.
