- the top portion 63 of the front insert 62 of at least one embodiment comprises a cooperatively structured and substantially angled configuration so as to abut or fit within the angled configuration of the front cavity, as defined by adjacent surfaces 42', 44'.
- the front insert 62 of at least one embodiment of the present invention is structured to provide additional support, cushioning, or comfort to the front portion of the footwear assembly 10 and the user's foot. More in particular, as the user rolls or rocks onto the front portion of the footwear assembly 10 and/or the front portion 52 of the outsole component 50, the front insert 62 is structured to provide support and/or comfort to the user.
- At least one embodiment of the present invention comprises a rear insert 66 at least partially disposed within a rear cavity between the rear portion 45 of the midsole component 40 and a rear portion 55 of the outsole component 50.
- the rear insert 66 comprises a top portion 67 which is cooperatively structured to connect to, abut with, or at least partially fit within, the rear cavity of the midsole component 40.
- the rear cavity of the midsole component 40 is disposed proximate to the rear portion 45 of the midsole component 40 and is at least partially defined by adjacent rear surfaces, such as, a lower surface or ledge 42" of the upper portion 42, and a rear surface or edge 44" of the lower extension portion 44.
- the upper surface 67 of the rear insert 66 comprises a substantially and sharply angled configuration.
- the rear cavity of the midsole component 40 defined by surfaces 42" and 44" is cooperatively structured to define a similar substantially angled configuration.
- the rear insert 66 of at least one embodiment is structured to provide additional support, cushioning, or comfort to the rear portion of the footwear assembly 10 and the user's foot. More in particular, as the user rolls or rocks onto the rear portion of the footwear assembly 10 and/or the rear portion 55 of the outsole component 50, for instance proximate the user's heel, the rear insert 66 is structured to provide support and/or comfort to the user .
- At least a portion of the outsole component 50 is connected to the lower extension portion 44 of the midsole component 40, and in particular, at a location in between the front and rear inserts 62, 66.
- the lower surfaces 64, 68 of the front and/or rear inserts 62, 66 are structured to define an at least partially curved or arcuate configuration.
- the outsole component 50 of at least one embodiment of the footwear assembly 10 is connected to the lower surfaces 64, 68 of the front and rear inserts 62, 66. Accordingly, the at least partially curved or arcuate configuration of the lower surfaces 64, 68 of the front and/or rear inserts 62, 66 are thus structured to facilitate the arcuate contour of the outsole component 50 when assembled.
- each of the layers or components for instance, the insole component (s) 30, 30', midsole component 40, outsole component 50, and front and/or rear inserts 62, 66, are separate and prior to assembly are initially detached from one another.
- Such a configuration and structure provides a footwear assembly 10 that minimizes impact on certain portions of the user's body or foot. For instance, because of the initially disjointed nature of the separate layers or components, an impact at one point of the footwear assembly 10 during use does not travel well to other points. Thus, an impact at the heel of the footwear assembly 10 is less likely to travel to other portions of the footwear assembly 10 and/or the user's body.
