| 摘要 |
A composite sole structure for an article of footwear includes a bottom component and an intermediate component. Each of the intermediate component and the bottom component includes a protruding portion that forms a concave contour on the top surface and a corresponding convex contour on the bottom surface of the component, where the protruding portion includes at least a first portion that forms a continuous trough at least from a medial side of the forefoot region, e.g., from a medial side of a toe split, to a lateral side of the heel region, e.g., a heel strike region. The bottom component further includes a variable thickness profile that forms a continuous ridge on the bottom surface, the ridge extending from the medial side of the forefoot region to the lateral side of the heel region, the ridge being substantially aligned with the first portion of the protruding portion of the intermediate component and the bottom component. |

1. An article of footwear, comprising:
a sole structure, the sole structure comprising:
an intermediate component; anda bottom component, the sole structure having a toe region, a forefoot region, a midfoot region, and a heel region, the sole structure having a medial side and a lateral side, the intermediate component having a top surface, a bottom surface, and a protruding portion that forms a concave contour on the top surface of the intermediate component and a corresponding convex contour on the bottom surface of the intermediate component, the protruding portion including at least a first portion that forms a continuous trough at least from the medial side of the forefoot region through the midfoot region to the lateral side of the heel region, the bottom component having a top surface, a bottom surface, and a protruding portion that forms a concave contour on the top surface of the bottom component and a corresponding convex contour on the bottom surface of the bottom component, the protruding portion including at least a first portion that forms a continuous trough at least from the medial side of the forefoot region through the midfoot region to the lateral side of the heel region, the top surface of the bottom component contacting the bottom surface of the intermediate component, the first portion of the bottom component being aligned with the first portion of the intermediate component, and the bottom surface of the bottom component being configured to engage a ground surface, the bottom component further having a variable thickness profile that forms a continuous ridge on the bottom surface of the bottom component, the ridge extending from the medial side of the forefoot region through the midfoot region to the lateral side of the heel region, the ridge being substantially aligned with the first portion of the intermediate component and the first portion of the bottom component. |
