Definitions

  • the present invention relates to footwear, and more particularly to an ergonomic footwear for helping wearers walk with improved smoothness.
  • 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.
  • 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.
  • 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 further supporting wearers' walking smoothness.
  • the existing grooves are typically randomly distributed over the bottom surface of the outsole, the force-exerting regions may not necessarily act on the grooves when the wearers are treading. Thus the conventional footwear is ineffective in improving wearers' walking smoothness.
  • the primary objective of the present invention is to provide an ergonomic footwear, which is helpful to preventing a human foot sole from sliding with respect to the outsole, thereby enhancing stability of treading of the human foot sole and further improving wearers' walking smoothness.
  • an ergonomic footwear primarily comprises an outsole that has an inner arch segment, an outer arch segment, a heel segment located behind the outer arch segment, a toe segment located before the outer arch segment and corresponding to human first, second, third, fourth, and fifth toes, and a metatarsus segment located between the outer arch segment and the toe segment, all corresponding to regions of a human foot sole, respectively, wherein the toe segment includes an inner toe segment and an outer toe segment, and the metatarsus segment includes an inner metatarsus segment and an outer metatarsus segment.
  • the footwear is characterized in the outsole having a top surface, which includes 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.
  • the contacting portion is located in at least one of the heel segment, the outer arch segment, the metatarsus segment, the inner metatarsus segment, the outer metatarsus segment, the toe segment, the inner toe segment, and the outer toe segment.
  • the contacting portion of the footwear different from the datum plane in the top surface of the outsole in elevation can prevent a walking wearer's foot sole from sliding with respect to the outsole, so as to make the wearer's foot sole tread more stably and further make the wearer walk more smoothly.
  • the contacting portion of the outsole may be a top-surface depression depressed from the top surface of the outsole, or a top-surface bulge protruding from the top surface of the outsole.
  • the outsole has at least one bottom-surface recesses formed at a bottom surface thereof and corresponding to the top-surface depression or the top-surface bulge.
  • the disclosed footwear additionally has a cushioning function.
  • the contacting portion of the outsole is a top-surface depression
  • the contacting portion is preferably located in at least one of the metatarsus segment, the inner metatarsus segment, the outer metatarsus segment, the toe segment, the inner toe segment, the outer toe segment, the outer arch segment, and the heel segment.
  • the contacting portion of the outsole is a top-surface bulge
  • the contacting portion is preferably located in the metatarsus segment, the inner metatarsus segment, the outer metatarsus segment, the toe segment, the inner toe segment, the outer toe segment, the heel segment, and/or the inner and outer arch segments.
  • the disclosed ergonomic footwear may further comprise a pad containing but not limited to a midsole, an insole or other thin lining deposited on the top surface of the outsole, or may comprise a midsole deposited on the top surface of the outsole and an insole deposited on the top surface of the midsole.
  • the top surface of the midsole includes a datum plane and at least one contacting portion different from the datum plane in elevation.
  • the contacting portion is located corresponding to at least one of the heel segment, the inner arch segment, the outer arch segment, the metatarsus segment, the inner metatarsus segment, the outer metatarsus segment, the toe segment, the inner toe segment, and the outer toe segment of the outsole.
  • the contacting portion of the midsole is preferably configured to match the contacting portion of the outsole.
  • the contacting portion of the midsole may be a top-surface depression depressed from the top surface of the midsole, or a top-surface bulge protruding from the top surface of the midsole.
  • the top surface of the insole has at least one hollow bowl or at least one hollow dome that is located corresponding to at least one of the heel segment, the inner arch segment, the outer arch segment, the metatarsus segment, the inner metatarsus segment, the outer metatarsus segment, the toe segment, the inner toe segment, and the outer toe segment of the outsole.
  • the hollow bowl has a sagged surface integrally depressed from the top surface of the insole and a raised surface corresponding to the sagged surface and integrally raised from the bottom surface of the insole.
  • the hollow dome has a raised surface integrally raised from the top surface of the insole and a sagged surface corresponding to the raised surface and integrally depressed from the bottom surface of the insole.
  • the insole has the hollow bowl and the hollow dome configured to match the contacting portion of the outsole.
  • the contacting portion of the outsole is a top-surface depression

  • the raised surface of the hollow dome of the insole may have a reinforcing groove
  • 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.
  • 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, proceeding between the metatarsus segment and the outer arch segment transversely, and reaching a place near a periphery of the inner metatarsus segment; and or starting from a place near a periphery of the heel segment, extending transversely along the heel segment to a place near an opposite periphery of the heel segment.
  • the bottom surface of the outsole has at least one bottom-surface trough corresponding to the top-surface trough. This configuration can improve the flexibility of the outsole and further ensure the wearers' walking smoothness.
  • the outsole may further have a protuberance protruding from the top surface of the outsole. The protuberance is located the inner arch segment for supporting the wear's foot sole at the inner arch, thereby facilitating stable tread of the wearer's sole and further enhancing the wearer's walking smoothness.
