Multi-function variable healthcare shoe

Abstract

A multi-function variable healthcare shoe is provided, including a foot pad having an air sack foot pad that obeys pumping principles, an intake valve disposed on an inner side of a rear bottom portion of the air sack, and an exhaust valve disposed on an inner side of a toe portion of the air sack. A plurality of non-slip protrusions are disposed in front of the air sack. A curved and protruded air guide turns to an external portion of a venting slot for guiding air to flow through a slot disposed on a bottom portion and a protection edge to a topline to form a ventilation system. Therefore, air keeps flowing through and ventilating in the multi-function variable healthcare shoe. The foot pad has a massage cover. The foot pad is full-sized or half-sized.

What is claimed is: 
     
         1 . A multi-function variable healthcare shoe, which is a loafer shoe having an invisible shoehorn or a tongue sleeve shoe having an invisible shoehorn, the multi-function variable healthcare shoe comprising:
 a full-sized or half-sized foot pad having an air sack that obeys pumping principles, an intake valve disposed on an inner side of a rear bottom portion of the air sack, and an exhaust valve disposed on an inner side of a toe portion of the air sack;   a plurality of non-slip protrusions disposed in front of the air sack;   a venting slot penetrating the foot pad;   a slot disposed on a bottom portion of the foot pad and a protection edge of the foot pad and communicating with the venting slot; and   a curved and protruded air guide disposed in front of the air sack and turning to an external portion of the venting slot for guiding air to flow through the slot disposed on the bottom portion and the protection edge to a topline to form a ventilation system.   
     
     
         2 . The multi-function variable healthcare shoe of  claim 1 , wherein the foot pad is a ventilating and breathing foot pad, a full-sized foot pad having a palm-shaped air sack, or a half-sized multi-function variable foot pad. 
     
     
         3 . The multi-function variable healthcare shoe of  claim 1 , wherein the foot pad has an invisible raised structure.

         5 . The multi-function variable healthcare shoe of  claim 1 , wherein the foot pad is half-sized, and has a concave-convex structure that is engageable with a shoe bottom or a full-sized pad bottom to form another full-sized foot pad. 
     
     
         6 . The multi-function variable healthcare shoe of  claim 1 , further comprising an arch strip disposed on an inner side of a middle portion of a shoe bottom for gradually filling the air sack to compromise an elasticity and air flow rate of the air sack. 
     
     
         7 . The multi-function variable healthcare shoe of  claim 1 , further comprising a fry-pan-shaped depression disposed on a shoe bottom and an elastic pad bottom received in the fry-pan-shaped depression. 
     
     
         8 . The multi-function variable healthcare shoe of  claim 1 , further comprising a fry-pan-shaped depression disposed on a shoe bottom, and a hard pad bottom received in the fry-pan-shaped depression, along with a through hole of the foot pad, wherein a thumb screw is inserted and rotates in the hard pad bottom to adjust massage strength. 
     
     
         9 . The multi-function variable healthcare shoe of  claim 1 , wherein the loafer shoe further comprises a pneumatic block, a compressive block or a pocket block disposed on an inner side of a foot protection cover thereof. 
     
     
         10 . The multi-function variable healthcare shoe of  claim 1 , wherein the tongue sleeve shoe is a low leather shoe and a low sport shoe and comprises an elastic band disposed on a tongue thereof, the elastic band having a hook on one end thereof to be hooked into a hook hole on a facing.
