This invention relates to soles and footwear incorporating such soles. A sole portion (11) defines a number of air voids (16), each of which has an upper opening (17), formed by the necks of the heads of the moulding tool used to define the voids. In the preferred embodiment a cone (20) surrounds the opening (17). Each cone (20) can be compressed by the application of an upper, when a piece of footwear is being formed so that the cone pinches the opening (17) preventing filler from entering the void (16). |
