Aduckbill,bearpaw orcow's mouth was a style of shoe with a broad toe which was fashionable in the 15th and 16th centuries. This style started withCharles VIII of France, who had anextra toe, and was later worn byHenry VIII of England. It replaced the excessively long toe of thepoulaine but also tended to become impractical, as it became enlarged with stuffing and horns and so could be a foot wide, giving the wearer a waddling gait. It might also be adorned with slashes to show the fine lining andsumptuary laws were introduced to restrict all these excesses.[1][2] Duckbill shoes were rounded like aduck's bill; cowsmouth shoes widened abruptly at the toes; and bearsclaw shoes had slashes parallel to the toes, so the toe could expand laterally.
There is asurviving design for a duckbill shoe byAlbrecht Dürer; he describes it as made on an absolutely straight, symmetric last, and as having an entirely flat sole of two thicknesses of leather. The shoes he designed were also to have straps over the instep.[3]
