A removable protective innersole for safety footwear includes a body made of a plastic material, a puncture-resistant sheet made of metal or plastic, a protective toe-cap made of metal or plastic, and a lining. The lower part of the body is provided with protrusions and/or grooves, suitable for creating a series of recesses between said protective insole and the midsole of the shoe.
