Abstract
A footwear product, such as a rubber boot, has protective plates disposed to prevent the penetration of sharp objects into a wearer's foot. A first rigid protective plate is embedded in the sole, and a second rigid protective plate is disposed to cover an inside side portion of the instep. In combination, the plates prevent penetration of a sharp object into the wearer's foot when the wearer steps on the object.
