A sturdy shoe is a type of footwear that is designed to be durable and long-lasting. The term 'sturdy shoe' can refer to a variety of different styles, including the OXFORD, BROGUE, and BROGAN. An OXFORD is a type of low-heeled shoe with laces, typically made of leather. A BROGUE is a type of shoe with decorative perforations and serrations on the toe cap and sides. Finally, a BROGAN is a type of heavy-duty boot with a thick sole and lacing up the front. All three of these styles are considered to be sturdy shoes, as they are designed to be strong and long-lasting.
