wherein the first location and second location are disposed on opposing sides of the containment strap such that the central region defines a guide to slidably receive the containment strap between the ancillary piece of material and the main upper body, and wherein the containment strap makes flush contact with the main upper body on an inner side of the containment strap and makes flush contact with the ancillary piece of material on an outer side of the containment strap when the containment strap is provided within the guide;
wherein the upper further comprises a plurality of eyelets disposed on opposite sides of the throat opening and wherein the containment strap includes an aperture that is configured to align with one of the plurality of eyelets such that a lace may pass through the aperture and aligned eyelet; and
wherein the containment strap is not permanently attached to the main upper body within the guide or between the guide and the throat opening.
