Embodiment Construction

[0023] Referring to FIGS. 3 and 4, the first preferred embodiment of a shoe 30 according to the present invention is shown to include a first shell portion 31, a second shell portion 32, and an outsole unit 33. The outsole unit 33 includes a midsole 331 and an outsole 332 connected to a bottom surface of the midsole 331.

[0024] The second shell portion 32 is more flexible than the first shell portion and is composed of a plurality of pieces. In this embodiment, the second shell portion 32 includes a front part 321 and an instep part 322. The second shell portion 32 complements the first shell portion 31 to form an upper, and is mechanically connected to the first shell portion 31.

[0025] As shown in FIG. 4, the first shell portion 31 includes a sole part 312 which is secured to the midsole 331 and which has at least a heel region 3121, and a surrounding wall 310 which projects upward from a periphery of the heel region 3121 and which has a substantially U-shaped cross-section that t...

Abstract

A shoe includes a first shell portion, and a second shell portion complementing the first shell portion to form an upper. The second shell portion is more flexible than the first shell portion and is mechanically connected to the first shell portion. The first shell portion includes a surrounding wall of substantially U-shaped cross-section which is adapted to extend around the wearer's heel. The surrounding wall includes two opposite side wall sections that have frontmost ends posterior to the ball of the foot and anterior to the plantar arch of the foot.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to a shoe, more particularly to a shoe which has first and second shell portions, which is capable of providing ankle protection, breathability, and good bendability, which can reduce molding costs, and which is relatively light in weight. [0003] 2. Description of the Related Art [0004] Referring to FIG. 1, a conventional shoe 10 is shown to have an outsole unit 11, a shell 12 provided on and connected to the outsole unit 11, and an upper 13 connected to an upper edge of the shell 12 by stitches. In general, the shell 12 is formed from a relatively rigid waterproof material such as rubber, TPU or TPR, and is formed to have a surrounding wall 121 that is connected to an outer periphery of the outsole unit 11, and that extends from a heel part of the shoe 10 to the toe part of the shoe 10. While the shell 12 provides the shoe 10 with a measure of water-tightness, it affects the breathability and ...
