Benefits of technology

"The present invention is a footwear with a double-density insole that is elastically deformable to offer wearing comfort. The insole has a first layer for contact with the user's foot and a second layer bonded to the first layer at the bottom side. The first layer has a hardness greater than the second layer and includes a base and a plurality of ribs raised from the top side of the base. The second layer is compressed and elastically deformed when the user's foot touches the insole, providing a buffering effect and enhancing the wearing comfort of the footwear."

Problems solved by technology

However, this design is quite simple and cannot satisfy the user's demand for conform wearing.

Embodiment Construction

[0009]Referring to FIGS. 1˜3, a piece of footwear, for example, a paddle slipper 10 in accordance with a first embodiment of the present invention is shown comprising an insole 20, an outsole 30 and an upper vamp 40.

[0010]The insole 20 comprises a first layer 21 for direct contact with the sole of the user's foot, and a second layer 22 bonded to the bottom side of the first layer 21. The second layer 22 is a flat sheet member. The first layer 21 has a base 212 and a plurality of ribs 214 raised from the top side of the base 212. The ribs 214 extend transversely from the left side of the insole 20 to the right side thereof and equally spaced. The distance L between the peak of each rib 214 and the base 212 is about 2˜4 mm. The first layer 21 and second layer 22 of the insole 20 can be made from EVA (ethylene vinyl acetate copolymer), PU (polyurethane) or PVC (polyvinyl chloride). However, the material for the first layer 21 has a relatively higher density than the material for the se...

Abstract

A footwear includes an insole having a first layer for the contact of the sole of a user's foot and a second layer bonded to the first layer at a bottom side. The first layer comprises a base and a plurality of ribs raised from a top side of said base and has a hardness greater than the second layer. An outsole bonds to the bottom side of the insole for contacting the ground. When a user wearing the footwear is paddling, the insole is elastically deformed and the ribs are elastically curved to buffer the pressure applied by the user, enhancing wearing comfort.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to footwear and more particularly, to footwear with a double-hardness insole that offers wearing comfort.[0003]2. Description of the Related Art[0004]A footwear generally comprises an insole, an outsole and an upper vamp. The insole is for direct contact with the sole of the user's foot. The outsole is bonded to the bottom side of the insole for contacting the ground. The upper vamp defines with the insole an accommodation space for accommodating the user's foot.[0005]Normally, the outsole has a relatively higher hardness to provide a wear resistant property and a support function. The insole has a relatively lower hardness to buffer the pressure from the sole of the user's foot. However, this design is quite simple and cannot satisfy the user's demand for conform wearing. Therefore, an improvement in this regard is necessary.SUMMARY OF THE INVENTION[0006]The present invention has been acco...
