The sole for footwear has base (2) with a raised edge (3). The sole has a groove (4) in the base or the edge to allow assembly with the upper. The groove can be formed over all or some of the inner or outer face of the base or edge. The groove can have a rectangular or semi-circular profile. The inner face of the groove can be vertical to form an extension of the inner surface of the edge.
