Footwear with enhanced wearing comfortability, stability and orthotic foot support are disclosed. The footwear comprises built-in intrinsic midsole, anatomically shaped footbed having a functional arch concavity on a medial side, and deep heel cup. The built-in intrinsic midsole provides ideal foot support and function. Raised sidewalls accentuate a deep heel cup, which controls and matches the natural anatomic shape of the foot. The midsole is made by direct single density injection with integrated orthotic contour. The direct injection midsole to upper creates a strong bond, and resolves a potential of delaminating soles. Furthermore, it eliminates the need and cost of cementing, and improves instant fit/comfort.

The present disclosure provides an upper for an article of footwear. The upper may include a knit element defining a portion of at least one of an exterior surface of the upper and an opposite interior surface of the upper. The interior surface may define a void. A tongue and the knit element may have a common yarn, and the tongue may extend through a throat area of the upper. The tongue may comprise a lateral edge, a medial edge, and a forward portion. At least one of the lateral edge and the medial edge of the tongue may be unsecured to the knit element. The tongue and the knit element may comprise a common yarn at least at the forward portion of the tongue.

The footwear includes a base having a toe portion, a heel portion opposing the toe portion, a base left and right side, and a bottom surface to engage the ground when worn by a user. The footwear additionally includes a base top surface opposing the base bottom surface, a toe box permanently coupled to the toe portion of the base at the top surface, and a counter permanently coupled to the heel portion of the base at the top surface. The footwear further includes a left and right support structure permanently coupled to the top surface of the base between the toe box and the counter on each side of the base, and a detachable left and right panel configured to detachably connect to the respective left and right support structure.

A shoe capable of adjusting heel height includes a front bracket, a rear bracket, a telescopic linkage rack, a telescopic support member, a linking member and a locking mechanism. The rear bracket is rotatably connected to the front bracket. The telescopic linkage rack is pivotally connected to the rear bracket, and can be telescoped with the movement of the rear bracket. The telescopic support member is fixedly connected to the telescopic linkage rack, and can be simultaneously telescoped in the same direction and in the same proportion with the telescoping degree of the telescopic linkage rack. The linked member is pivotally connected to the front bracket and the telescopic support member, and arranged spaced to the rear bracket, and the linked member is spaced to the rear bracket. The locking mechanism can removably fix the telescopic support member for limiting the telescopic support member.

An upper may include a first knitted portion configured to form an outer surface of the upper, a second knitted portion configured to form an inner surface of the upper, where the second knitted portion is at least partially coextensive with the first knitted portion, an interstitial space between the first knitted portion and the second knitted portion, and a knitted connection structure connecting the first knitted portion to the second knitted portion. The knitted connection structure may extend at least partially along at least one of a tongue and a collar of the upper, and the second knitted portion may include at least one double jersey knit structure that is coextensive with the first knitted portion.
