Provided is functional footwear that restrains bad smell and the propagation of germs due to long-time usage of the footwear while maintaining a correct posture of a wearer by cushioning impact applied to feet and distributing pressure. The functional footwear includes a first groove formed in a length direction at a predetermined portion of a midsole, a second groove formed in a width direction of the midsole to be connected with the first groove, a recess formed inside the second groove and perfume emitting materials or antibacterial materials inserted into the recess.

1 . A functional footwear including an outsole, a first midsole located on the outsole to be attached to the outsole, and a second midsole located between the outsole and the first midsole, comprising:
 a plurality of first air passages formed on left and right sides in a length direction of the first midsole   a second air passage connecting the first air passage in the length direction of the first midsole and   a third air passage connecting the first air passages having bilateral symmetry,   wherein a functional material including perfume emitting or antibacterial materials is fixed to the third air passage by an adhesive means, and an insole forming a fine thorough hole is located on the first midsole, thereby releasing air containing the components of the functional material outside the insole through the air passages and the thorough hole of the insole by motions of a man during walking.   
     
     
         2 . The functional footwear of  claim 1 , wherein an insertion groove is formed in the third air passage at a regular interval and the functional material is fixed to the insertion groove by the adhesive means. 
     
     
         3 . The functional footwear of  claim 1 , wherein water does not pass through the air passage but air is released from the air passage by sealing a portion, in which the first, second and third air passages are formed, with an air-permeable waterproof material. 
     
     
         4 . The functional footwear of  claim 2 , wherein water does not pass through the air passage but air is released from the air passage by sealing a portion, in which the first, second and third air passages are formed, with an air-permeable waterproof material. 
     
     
         5 . The functional footwear of  claim 1  wherein a bottom of the functional footwear has a round shape. 
     
     
         6 . The functional footwear of  claim 2 , wherein a bottom of the functional footwear has a round shape. 
     
     
         7 . The functional footwear of  claim 3 , wherein a bottom of the functional footwear has a round shape. 
     
     
         8 . The functional footwear of  claim 4 , wherein a bottom of the functional footwear has around shape.
