The sole (1) being affected in at least one of the forefoot (2) and/or midfoot (3) regions by at least one recess (9) extending transverse to the longitudinal axis (X), at least one insert (10) at least partially housed in the at least one recess (9), the insert (10) comprises at least one elongated extension (11) having a main development along a first extension axis (E1) and the first extension axis (E1) being transverse to the longitudinal axis (X). The insert (10) is formed from a first material (P1), and the forefoot (2) and/or midfoot (3) region of the main part (4) are formed from a second material (P2), with the first material (P1) having a higher modulus of elasticity and/or a greater hardness than the second material (P2) and the at least one elongated extension (11) comprising a support end (11a1) being perpendicular to the longitudinal axis (X).
