But As'ad knows better

While throwing your shoes at someone would be considered insulting in any culture, in the Arab world, the gesture has a special potency: footwear is commonly used to deliver both verbal and physical insult. In Egypt, for example, many popular and colourful insults include the mention of shoes: "You son of a shoe", "You have shoes for brains", "You'll follow me like an old shoe", etc.

Although their offensiveness is largely lost in translation, delivered in Arabic they are a sure-fire way of getting people's backs up. But why this obsession with shoes? Does it reflect a weird foot fetish? One shoe-lover I know found the whole episode a terrible waste of a pair of perfectly good shoes.

The offensive power of shoes probably has something to do with the lowly status of the shoe, which resides, downtrodden with its face in the dirt, all the way at the bottom of the clothing hierarchy. That's why worshippers leave their shoes outside mosques.

That is probably why hot-blooded working-class Egyptian women sometimes take off their shoes or slippers to hit men who harass them on the street: to show that the man belongs in the gutter and is not worthy of contempt. Bizarrely and inexplicably, slapping someone on the back of the neck and calling them a "nape" ('afa) is also a huge insult.
