What did Roman soldiers wear?

Romans had different footwear for different purposes. Indoors they wore either slippers or sandals. Outside they wore shoes or boots. (It was considered improper to wear sandals outdoors and rude to wear shoes indoors.) The military had a special type of boot with hobnails or studs on the soles.
Indoors, the Romans wore open-toed sandals. However they preferred to wear shoes that covered their toes. Both men and women wore leather sandals or leather boots in cold weather.
