Article of footwear with ribbed footbed

摘要

An article of footwear configured for prolonged casual and non-casual uses having an upper configured for easy installation and removal of the article of footwear with or without the use of fasteners, a sole, and a substantially continuous series of alternating ribs and grooves on a footbed of the sole extending from a forefoot region to a heel region. The ribs and grooves have base widths that are greater in an arch region of the footbed than the forefoot and heel regions of the footbed. The series of alternating transverse ribs and grooves are oriented from a lateral side region of the footbed to a medial side region of the footbed.

1. An article of footwear comprising:
a sole comprising an outsole and a footbed element configured to support a foot away from the outsole; a plurality of substantially transverse ribs formed on the footbed element so that a groove is disposed between adjacent ones of the ribs and the plurality of substantially transverse ribs are exposed to the foot, each of the substantially transverse ribs extending across the footbed element from a lateral edge of the footbed element to a medial edge of the footbed element, the plurality of substantially transverse ribs including a substantially continuous series of ribs and grooves extending from a forefoot end portion of the sole to a heel end portion of the sole; a forefoot set of the substantially transverse ribs disposed at a forefoot region of the footbed element having a first geometry including a first rib height, a first base width and a first spacing between adjacent ribs; a heel set of the substantially transverse ribs disposed at a heel region of the footbed element having a second geometry including a second rib height, a second base width and a second spacing between adjacent ribs; an arch set of the substantially transverse ribs disposed at an arch region of the footbed element having a third geometry that differs from the first and second geometries, the third geometry including a third rib height, a third base width and a third spacing between adjacent ribs; wherein each of the plurality of substantially transverse ribs forms an angle of inclination measured from an axis running through a center of the rib and substantially perpendicular to the outsole, and wherein:
the angle of inclination of the ribs in the forefoot set of the substantially transverse ribs increase moving rearward along the footbed element from ribs being angled toward a toe edge of the forefoot region to ribs that are oriented substantially perpendicular to the outsole; andthe angle of inclination of the ribs in the heel set of the substantially transverse ribs increase moving forward along the footbed element from ribs being angled toward the forefoot region to ribs that are oriented substantially perpendicular to the outsole.
