An integrated injection forming shoe midsole having a dual-layer pad includes a midsole and a dual-layer pad integrally formed by an injection forming process to form a tightly bonding between the midsole and the dual-layer pad. The dual-layer pad has a softer pliable pad on the upper layer and a harder and resilient cushion pad on the lower layer, and a buffer section corresponding to the heel location. Through the buffer section and the upper and lower-layers which have different material properties, the midsole may provide wearers more comfortable feeling and shock-absorbing bouncing resilience when touching ground surface.

Described herein are a spoiler for vehicles and a method of manufacturing the spoiler. The spoiler has a first surface and a second surface which define an appearance of the spoiler, and a hollow part defined in the spoiler. The spoiler includes a reinforcing member which is formed integrally with the second surface and has a frame defining an appearance of the reinforcing member and holes formed in the reinforcing member, and a support unit which is secured to cover the holes of the reinforcing member and an outer surface of the frame, thus supporting the reinforcing member to the second surface. The reinforcing member is formed integrally with the second surface through blow molding.

An electrical insole or outsole is provided to increase foot support. The insole is attached to the top of the sole body, whereas the outsole is attached to the bottom of the sole body. The insole or outsole has a raised front portion to shift some weight rearward to the center of the foot. The back portion of the insole is either raised or lowered, depending on the shoe heel height, to shift some weight forward to the center of the foot.

A shoe that reduces the likelihood of stress fractures occurring in the wearer's metatarsals. The shoe includes a midsole made of (i) a stress modulation layer that is made of material of relatively high duromoeter in the region of the first, fourth and fifth metatarsal, and a material of medium durmoeter in the region of the second and third durometer, and (ii) a stress moderation layer made mostly of a material of relatively low durometer.

Footwear including a sole having a front and a back for supporting a bottom of a foot. A heel cup at the back of the sole receives and supports a heel of the foot. The heel cup has a bottom for further supporting the bottom of the foot and a side wall extending up from the bottom. The side wall has a generally concave rear section for receiving and supporting the back of the heel and opposite side sections extending forward from the rear section. The recess in the rear section of the side wall of the heel cup is offset laterally from a longitudinal central vertical plane of the heel cup. The recess is sized for accommodating the rearwardly protruding lateral posterior portion of the calcaneus of the foot.
