A structure of a toe cap and a shoe having the toe cap embedded which does not disturb foot movement such as walking while protecting a toe against lateral collision with an object such as a wheel of a dolly includes a cup-shaped shell body which is formed by connecting a front end wall, bilateral side walls and an upper face wall with a gentle curved face, and an extension side wall disposed at least to one side wall as rearwardly extending a rear end edge of the side wall. The shoe having the toe cap embedded can sufficiently protect the toe even when an impact is applied from the outer side (i.e., the little toe) direction of the toe of which protection is not sufficient with a normal toe cap embedded shoe.
