Benefits of technology

[0015]In addition, the raised surface of the hollow dome of the insole may have a reinforcing groove, and the sagged surface of the hollow bowl may have a reinforcing rib for preventing the hollow dome and the hollow bowl from deformation due to long time of use.
[0016]In one embodiment of the ergonomic footwear of the present invention, the top surface of the outsole may have at least one top-surface trough near the at least one contacting portion. The top-surface trough is formed as starting from a place near a front periphery of the toe segment, proceeding between the inner and outer toe segments and going lengthwise toward the heel segment; or starting from a place near a periphery of the outer toe segment, proceeding between the toe segment and the metatarsus segment transversely, and reaching a place near a periphery of the inner toe segment; or starting from a place near a periphery of the outer metatarsus segment

Problems solved by technology

However, since the existing grooves are typically randomly distributed over the bottom surface of the outsole, the force-exerting regions may not n

first embodiment

[0053]Referring first to FIG. 1, according to the present invention, an ergonomic footwear 1 primarily comprises an outsole 10.

[0054]The outsole 10 is made of a PU foam material and possesses resilience. Of course, in practical manufacturing, the outsole 10 may be made of any materials known to be used in making footwear outsoles, such as latex or thermoplastic rubber (TPR). As shown in FIG. 2, the outsole 10 may be divided, according to regions of a human foot sole that apply treading force, into an inner arch segment 19, an outer arch segment 11, a heel segment 12 that is located behind the outer arch segment 11, an inner toe segment 13 that is located in front of the outer arch segment 11 and corresponds to the human, an outer toe segment 14 that is located in front of the outer arch segment 11 and corresponds to the second through fourth toes, a toe segment 15 comprising the inner and outer toe segments 13, 14, a metatarsus segment 16 that is located between the outer arch segme...

third embodiment

[0058]Now referring to FIG. 11, in the present invention, the footwear 1 comprises the outsole 10 and a pad which is a midsole 30 in this embodiment. The outsole 10 is configured according to the above embodiments and thus needs not to be discussed in any length herein.

[0059]The midsole 30 is deposited on the top surface 101 of the outsole 10. As shown in FIG. 12, the top surface 301 of the midsole 30 includes a datum plane D, and a plurality of contacting portions 302 that are configured to be different from the datum plane D in terms of elevation. In FIG. 12, the contacting portion 302 are top-surface depressions 302a depressed downward from the top surface 301 of the midsole 30 and located corresponding to the outer arch segment 11, the heel segment 12, the toe segment 15 and the metatarsus segment 16 of the outsole 10, respectively. Also, as shown in FIG. 11, each of the top-surface depressions 302a are corresponding to one said top-surface depression 102a of the outsole 10, res...

fourth embodiment

[0061]Referring to FIG. 15, in the present invention, the footwear 1 comprises the outsole 10 and a pad which is an insole 40 in this embodiment. The detailed description of the outsole 10 is herein omitted for eliminating repetition.

[0062]The insole 40 is deposited on the top surface 101 of the outsole 10. As shown in FIG. 15 and FIG. 16, the insole 40 has a plurality of hollow bowls 402 corresponding to the outer arch segment 11, the heel segment 12, the toe segment 15 and the metatarsus segment 16 of the outsole 10, respectively, and corresponding to the top-surface depression 102a of the outsole 10, respectively. Additionally, in FIG. 15, the hollow bowls 402 each have a sagged surface 402a integrally depressed from the top surface 401 of the insole and a raised surface 402b that corresponds to the sagged surface 402a and integrally raised from the bottom surface of the insole 403. Thus, when a wear wears the footwear and walks, force-exerting regions of his / her foot sole can si...

Abstract

An ergonomic footwear at least includes an outsole having a top surface including a datum plane and at least one contacting portion such configured that a difference in elevation is formed between the contacting portion and the datum plane, wherein the contacting portion is located at a place to which a force is applied by a treading human foot sole of a wearer. Accordingly, such structure can prevent the wearer's sole from sliding with respect to the outsole, thereby facilitating stable treading of the wearer's sole and further enhancing the wearer's walking smoothness.

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]The present invention relates to footwear, and more particularly to an ergonomic footwear for helping wearers walk with improved smoothness.[0003]2. Description of Related Art[0004]Human walking is an arc-shaped motion achieved by using the hip joint as a pivot and the leg as a swinging arm and making the leg bent, lifted, and put on the ground. When treading against the ground, the human foot sole applies force from different regions as the treading motion proceeds. Therefore, the stableness of the treading process can have significant effect on the smoothness of the foregoing arc motion.[0005]Footwear manufacturers usually make outsoles from very flexible materials or form some spaced, transversely extending grooves at the bottom surface of the outsole in order to make the resultant outsoles more tensible, thereby improving the footwear in flexibility, for better conformity to the treading motion of the human foot sole, and ...
