Abstract

Provided is a heeling apparatus. The heeling apparatus includes a sole including a forefoot portion and a heel portion. The heel portion has an opening formed therein. In one embodiment, the sole includes a removable portion. The heeling apparatus further includes a wheel assembly including wheel rotably mounted to an axle and a mounting structure, wherein the wheel extends through the opening in the heel portion.

Claims

1. A dual durometer wheel for a heeling apparatus comprising:

a) a cylindrical outer tire made of a first urethane material and having an outer diameter, an axial bore and opposed end surfaces;

b) a cylindrical inner core made of a second urethane material that is harder than the first urethane material and having a central bore and opposed end portions, wherein the inner core is coaxially disposed within the axial bore of the outer tire;

c) annular bearings coaxially supported at each end portion of the inner core and having an outer diameter; and

d) an elongated axle extending through the annular bearings, the central bore of the inner core and beyond the opposed end surfaces of the outer tire, wherein the axle has rounded, non-threaded ends, wherein a ring clip is positioned around the axle near the annular bearing to ensure the annular bearing stays in position.

2. A dual durometer wheel as recited in claim 1, wherein the outer diameter of the annular bearing is less than half the outer diameter of the outer tire.

3. A dual durometer wheel as recited in claim 1, wherein the outer diameter of the annular bearing is greater than half the outer diameter of the outer tire.
