Heel structure with locating pegs and method of manufacturing an article of footwear

A footwear article includes an upper defining apertures spaced apart from one another in a first arrangement. A heel structure has a deformable element attached to a base. The deformable element has pegs spaced apart from one another in the first arrangement and extending through the apertures in the upper. A method of manufacturing a footwear article includes placing a deformable element between an inner layer and an outer layer of an upper and attaching the deformable element to a rigid base. The deformable element includes at least one peg extending outward toward the outer layer. The method includes inserting the peg through the outer layer so that the peg extends through the outer layer and is exposed at an exterior surface of the outer layer. After inserting the peg of the footwear element through the outer layer of the upper, the peg is secured at the exterior surface of the outer layer.
