These sophisticated women's shoes, with their slender high heels, show the popularity of Italian and French styles in Britain at this time. Called ‘slippers’, they showed off the woman's tiny foot and shapely leg under the shorter dresses that were then fashionable. The narrowest high heels had to be reinforced with metal spikes. This feature appeared again when stiletto heels came into fashion in the 1950s and 1960s.
