A mould assembly for moulding a heel on to a preformed sole comprises a heel breast mould member 6 a portion 12 of which is of resiliently deformable material so as to make a satisfactory seal between the breast member and the sole. Welt plates 16, 18 pivotally attached to the mould member 6 are connected by links 20, 22 having lost motion slots 24, 26, to mould retaining members 36, 38. These members 36, 38 are moved by linkage systems L1, L2 as in Specification 1,150,601. When the welt plates are moved to their closed position their leading edges 46, 48 engage inclined lower surfaces (45, 47) of a cam member 44 to hold the plates 16, 18 firmly during moulding. A base-plate 2 forms a tread surface of the mould cavity. A lasted upper/insole assembly including the sole (s) is mounted on a top mould member (14), Fig. 2 (not shown).
