The shoe of the previous period with its curved heel, squarish toe, and tie over the instep gave way in the second decade of the 18th century to a shoe with a high, curved heel.





Backless mules were worn indoors and out (but not on the street). Toes were now pointed. This style of shoe would remain popular well into the next period.
