A sole construction includes a cushion insert that is installable in the sole at different orientations to vary the support/cushioning characteristics of the sole. The sole construction may include a midsole defining a receptacle configured to receive the cushion insert in different orientations. The sole may be inserted into low-profile footwear having an outsole with a receptacle for retaining a corresponding differentiated heel portion of the sole. The sole may be included in a shoe construction having an outsole portion capable of bending or pivoting to provide access to the cushion insert for adjustment thereof. The sole may be included in a shoe construction having an outsole that defines an opening, through which the cushion insert may be accessed and manipulated. The cushion insert may include at least one channel that varies in depth about the insert so that different regions of the insert provide different support/cushioning characteristics.
