1. A footwear piece comprising:

  • a base section including an upper and a sole formed as a single part manufactured from a moldable foam material; and

    a strap section formed of a moldable material that is attached at opposite ends thereof to the upper of the base section with plastic connectors such that the moldable foam material of the strap section is in direct contact with the moldable material of the base section and pivots relative to the base section at the connectors;

    wherein the upper includes an open rear region defined by an upper opening perimeter, and wherein frictional forces developed by the contact between the strap section and the base section at the plastic connectors are sufficient to maintain the strap section in place in an intermediary position after pivoting, whereby the strap section lends support to the Achilles portion of the human foot inserted in the open rear region; and

    wherein the upper includes a substantially horizontal portion and a substantially vertical portion forming a toe region that generally follows the contour of a human foot, wherein the toe region tapers from an inner area of the base section where the larger toes exist to an outer area of the base section where the smaller toes exist; and

    wherein the sole includes a bottom surface having front and rear tread patterns longitudinally connected by a flat section.
