A coiled spring has a lower portion inserted in the respective hollow socket and an upper portion inserted in the respective collar.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a sandal device. More particularly, the present invention relates to a sandal device which can massage a foot of a user.

A sandal has an insole. A plurality of magnetic blocks can be disposed on the insole to massage a foot of a user. However, the user will feel uncomfortable after a long period of usage.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a sandal device which can massage a foot of a user and the user will feel comfortable while wearing the sandal device.

Accordingly, a sandal device comprises an outsole, an air cushion disposed on the outsole, and an insole disposed on the air cushion. The air cushion has two periphery flanges, a periphery spacing, a plurality of hollow protrusions formed on an upper portion of the air cushion and a plurality of hollow sockets formed on a lower portion of the air cushion to match the hollow protrusions. An elastic woven fabric and a shock-absorbing band are inserted in the periphery spacing of the air cushion. The shock-absorbing band has two periphery recesses for receiving the periphery flanges of the air cushion. Each of the hollow protrusions has a groove for receiving a magnetic block and a collar. A coiled spring has a lower portion inserted in the respective hollow socket and an upper portion inserted in the respective collar. An adhesive band encloses the elastic woven fabric and the shock-absorbing band.
