A shoe (L) for a left foot includes an outsole body (1). Both side slip
prevention projections (3a) and (3b) and a non-both side slip prevention
projection (5) are formed on a bottom surface of the outsole body (1). The
outsole body (1), the both side slip prevention projections (3a) and (3b)
and the non-both side slip prevention projection (5) are integrally formed
of a composition containing rubber or synthetic resin as a principal
component. Each of the both side slip prevention projections (3a) and (3b)
has a bottom surface to be a grounding surface, a toe side slip prevention
wall and a heel side slip prevention wall. The toe side slip prevention
wall is formed along a convex line in a direction of a toe. The heel side
slip prevention wall is formed along a convex line in a direction of a
heel. A shoe (R) for a right foot has a shape obtained by transversely
inverting the shape of the shoe (L) for the left foot.
