This shoe sole defines a front longitudinal groove that extends at least longitudinally between an inner side and an outer side of a front foot portion, and a first flex groove that is disposed forward of the hallux ball of the front foot portion and that extends at least transversely so as to intersect with the front longitudinal groove at an imaginary first point of intersection. A second angle between an outer flex portion of the first flex groove and the front longitudinal groove is larger than a first angle between an inner flex portion of the first flex groove and the front longitudinal groove. |
