Abstract: A heel shroud includes a bottom leg, and a side leg extending orthogonally from the bottom leg, forming an interior corner with the bottom leg. The heel shroud defines a first lateral surface, a second lateral surface, and the bottom leg includes a curved interior surface extending from the first lateral surface to the second lateral surface at least partially forming the interior corner. The first lateral surface defines a stress reduction geometry positioned at the interior corner, or includes a wear member that is attached to the side leg, or the bottom leg.

Abstract: A heel shroud includes a bottom leg, and a side leg extending orthogonally from the bottom leg, forming an interior corner with the bottom leg. The heel shroud defines a first lateral surface, a second lateral surface, and the bottom leg includes a curved interior surface extending from the first lateral surface to the second lateral surface at least partially forming the interior corner. The first lateral surface defines a first wear indicator or a stress reduction geometry that is disposed at the interior corner.
