Description of the Preferred Embodiments Referring to Fig. 1, a shoe 10 has an upper 12 defining a volume for enclosing a wearer's foot, and an outsole assembly 14 attached generally below the shoe upper.

Referring also to Figs. 2-7, the outsole assembly 14 includes an outsole 16 with an outsole body 18 of a suitable, wear-resistant, transparent material, defining a water-impervious outsole bottom surface 20 disposed for engagement with a walking surface when worn, an outsole upper surface 22 disposed generally in opposition to the shoe volume defined by the upper 12, and an outsole side surface 24 extending peripherally about the outsole, generally between the outsole bottom and top surfaces 20, 22. A grid member 26 (which may be a separate element, as shown, or which may be formed integrally with the outsole body, e.g. by molding) defines a plurality of apertures 28 at the outsole upper surface 22.

Articles 30 are disposed within one or more of the apertures 28, with the articles disposed at the outsole upper surface 22 being observable at the outsole bottom surface 20 through the outsole body 18 of transparent material. In a preferred embodiment, the transparent material of the outsole body 18 resembles amber and the articles 30 are three dimensional representations of insects, e.g. prehistoric insects; preserved therein.

Preferably, the bottom surface 20 defines a plurality of lugs 32 (e.g. embossed with three dimensional representations 33 of fossils that imprint on soft walking surfaces, or when a wet shoe sole is walked upon a dry surface), and apertures 28 at the outsole

upper surface 22 are disposed generally in registration with lugs 32.

Preferably, the articles 30 are sized in planar dimensions (i.e., length and width dimensions in an article plane, P,, generally parallel to a plane, P,, of the outsole upper surface 22) selected relative to planar dimensions of the corresponding aperture 28 to facilitate movement of the article 30 within the aperture 28 along the article plane, PA/ e.g. during walking or other movement of the wearer's feet.

The article 30 may also be sized in thickness dimensions (i.e. perpendicular to the article plane, PA) to restrict movement, e.g. flipping, of the article 30 within the aperture 28. In this regard, referring to Fig. 7, in the heel region, where a heel or rear aperture 34 has a relatively greater height dimension in the direction of article thickness, an insert element 36 having a shape generally corresponding to the predetermined shape of the heel aperture and a predetermined insert thickness, ti, is inserted into the heel aperture 34 containing an article in a manner to restrict movement of the article, e.g. in a direction perpendicular to the article plane PA.
