Abstract: An article of footwear (10) that includes a liner (30), an upper (14), and an insert (50). The liner has an inward surface (31) that encloses an inner void (18) for accommodating a foot, and an outward surface (32) that defines a rear shaft portion (38), a heel portion (36), and a sole portion (35). The upper has a midsole portion (42), and surrounds the rear shaft portion, the sole portion, and the heel portion of the liner. The insert is formed as a single body of material with increased hardness and stiffness relative to the upper. This insert is arranged between the liner and the upper, and includes a protruding portion (54), a heel counter (56), and a shank (58). The protruding portion extends upwards from the heel counter and along the rear shaft portion, and provides a guiding trajectory for a heel during insertion into the inner void.
