A shoe (10) comprising cushioning elements (20) housed in a tread sole (12, 50, 60) adapted to come into contact with the ground, the cushioning elements comprise a plurality of cushioning capsules (20) orientated in a manner such that they substantially follow a line on which the weight of a person is transferred during walking, i.e. a podalic line (40); the cushioning capsules (20) have different sizes and shapes that are geometrically similar to each other, constituting a series of modular elements adaptable to every shoe size and type.
