Readers with long memories may remember Sheilas’ Wheels’ blow-up doll passenger.

Well, hot on the heels (pun, unfortunately, intended) of that marvel, comes Sheilas’ Wheels’ latest creation for the gal about town, the Sheila Driving Heel.

An invention perhaps more at home in the Dragon’s Den than in the office, the heel is claimed to combine fashion with functionality.

A shame, then, that the manly Backchat could make no use of it.

Much more relevant were the revelations in the accompanying Sheila Safe Shoes report, which noted that it is illegal to drive barefoot in Scotland.
