A toe cap for safety and protection footwear for protection of the five toes of a foot according to a shoe last, in a single piece, such that the design of the toe cap allows for the protection of the 5 toes and such that it forms a rigid framework resistant to impacts, comprising: a front wall; two lateral walls (6, 8) joined at the top by means of a non-planar top surface; said front wall and two lateral walls (6, 8) ending at the bottom in an internally directioned flange; a rim that joins said two lateral walls (6, 8) and said top surface such that said rim recedes toward said front wall and terminates in a step, characterized by said rim having a curvature (D-D') which includes points P1, P2, P3, P4, wherein a mathematical formulas for the computation of measurements P1 to P4 of said curvature (D-D') are for men: P ⁢ 1 = K - 0 to 7 mm; P ⁢ 2 = K + 0 to 6 mm; P ⁢ 3 = K; P ⁢ 4 = K - 1 to 2 mm; and for women: P ⁢ 1 = K - 9 to 12 mm; P ⁢ 2 = K - 1 to 3 mm; P ⁢ 3 = K; P ⁢ 4 = K + 2 to 7 mm; where K is a constant that defines a point coinciding with a central line of said last and with a central line of the curvature of said toe cap and is defined as the distance to P3 that is equal to 1/3 of T + 5 mm + 10 mm wherein; T is the width of a heel of said last; and P1 is a point on a curve of said toe cap closest to a line of descent on the lateral wall to a first digit (big toe) on said last; P2 is a maximum point of curvature most pronounced toward the curvature of said last; P3 is a distance at which the curvature of said toe cap coincides with a central axis of said last; and, P4 is a point closest to a line of descent to a zone of the 5th digit (little toe) or external line of said last. a front wall; two lateral walls (6, 8) joined at the top by means of a non-planar top surface; said front wall and two lateral walls (6, 8) ending at the bottom in an internally directioned flange; a rim that joins said two lateral walls (6, 8) and said top surface such that said rim recedes toward said front wall and terminates in a step, characterized by said rim having a curvature (D-D') which includes points P1, P2, P3, P4, wherein a mathematical formulas for the computation of measurements P1 to P4 of said curvature (D-D') are for men: P ⁢ 1 = K - 0 to 7 mm; P ⁢ 2 = K + 0 to 6 mm; P ⁢ 3 = K; P ⁢ 4 = K - 1 to 2 mm; and for women: P ⁢ 1 = K - 9 to 12 mm; P ⁢ 2 = K - 1 to 3 mm; P ⁢ 3 = K; P ⁢ 4 = K + 2 to 7 mm; where K is a constant that defines a point coinciding with a central line of said last and with a central line of the curvature of said toe cap and is defined as the distance to P3 that is equal to 1/3 of T + 5 mm + 10 mm wherein; T is the width of a heel of said last; and P1 is a point on a curve of said toe cap closest to a line of descent on the lateral wall to a first digit (big toe) on said last; P2 is a maximum point of curvature most pronounced toward the curvature of said last; P3 is a distance at which the curvature of said toe cap coincides with a central axis of said last; and, P4 is a point closest to a line of descent to a zone of the 5th digit (little toe) or external line of said last. where K is a constant that defines a point coinciding with a central line of said last and with a central line of the curvature of said toe cap and is defined as the distance to P3 that is equal to 1/3 of T + 5 mm + 10 mm wherein; T is the width of a heel of said last; and P1 is a point on a curve of said toe cap closest to a line of descent on the lateral wall to a first digit (big toe) on said last; P2 is a maximum point of curvature most pronounced toward the curvature of said last; P3 is a distance at which the curvature of said toe cap coincides with a central axis of said last; and, P4 is a point closest to a line of descent to a zone of the 5th digit (little toe) or external line of said last.
