A Roman sandal is a type of footwear that has been around for centuries. It is characterized by its simple design and open-toe structure. However, there are other words that can be used to describe this type of sandal. For instance, one can use the term "gladiator sandal," which refers to the footwear's association with Rome's gladiatorial games. Another synonym is "lace-up sandal," which describes the method of fastening the sandal to the foot. Finally, "strappy sandal" is another term that can be used to describe the Roman sandal, owing to the criss-crossing straps that adorn the footwear.
