They sell absolutely everything
The first thing you discover when walking on the popular areas of Maputo is that the streets are a lively market. They sell absolutely everything, but the most abundant are the used shoes. If you have a pair or two of shoes that you carry find a spot on the street and wait for an interested party to buy them. Of course there are places where the sidewalks are crowded with shoes. There are miles of heels, shoes and slippers as organized regiments not let you pass. The best place to see this curious display is in the large square between Avenues 24 and Albert Luthuli Julho. Besides shoes you'll find a million things that will surely be more interesting.
