         5 . The insole of  claim 2 , wherein the protrusion is interchangeable between an original state in which the protrusion is perpendicular to the front surface and a deformed state in which the protrusion is pressed and a contacting state in which the cover or a portion of the column contacts with the front surface of the base. 
     
     
         6 . The insole of  claim 1 , wherein the coverage rate of the protrusions on the base ranges from 45% to 55%, and a distance between every two adjacent protrusions is 1 mm. 
     
     
         7 . The insole of  claim 1 , wherein the protrusion is perpendicular to the front surface of the base in an original state; after being pressed by an external force, the protrusion rotates for 360 degrees over a vertical axis of the protrusion which is perpendicular to the front surface of the base when the protrusion is in the original state; and after the external force is removed, the protrusion rebounds to the original state. 
     
     
         8 . The insole of  claim 1 , wherein the insole further comprises a hard middle layer arranged between the front surface and the rear surface of the base, and the hard middle layer can be folded up around a scroll after being pressed. 
     
     
         9 . The insole of  claim 1 , wherein the insole further comprises a thermal insulation layer adhered onto the protrusions. 
     
     
         10 . The insole of  claim 1 , wherein a shape of the insole is the same as that of a plane obtained by vertically projecting the whole foot sole of a wears on the base, and an area of the insole is equal to that of the plane; or, a shape of the insole is the same as that of a plane obtained by vertically projecting a part of the foot sole of the wearer on the base, and an area of the insole is equal to that of the plane. 
     
     
         11 . A shoe, comprising a shoe sole and a vamp connected with the shoe sole to form an accommodating space with an opening; the opening being used as a step-in opening of the shoe; the shoe sole comprising a front surface for corresponding to the foot sole of a wearer of the shoe and a rear surface for corresponding to the ground when the wear is walking; wherein the shoe further comprises a plurality of protrusions evenly arranged on the front surface and of the same heights; each protrusion comprises a column fixed on the shoe sole, and a height of the column protruding out from the front surface ranges from 1 to 7 mm; and a coverage rate of the protrusions ranges from 30% to 70%. 
     
     
         12 . The shoe of  claim 11 , wherein the protrusion further comprises a cover integrally formed with the column; the cover is arranged on one end of the column away from the front surface; the column is a solid cylindrical column or a solid prismatic column, and the height of the column is greater than a thickness of the cover. 
     
     
         13 . The shoe of  claim 11 , wherein a distance between every two adjacent protrusions ranges from 0.5 to 5 mm, and a diameter of the column ranges from 1 to 7 mm. 
     
     
         14 . The shoe of  claim 13 , wherein the protrusions are of the same shape and the same size, and the cover is hemispherical. 
     
     
         15 . The shoe of  claim 14 , wherein an elongation of the protrusion ranges from 200% to 400%; and the protrusion is made of silicone rubber having a Shore A hardness ranging from 10 to 50. 
     
     
         16 . The shoe of  claim 12 , wherein the protrusion is interchangeable between an original state in which the protrusion is perpendicular to the front surface and a deformed state and a contacting state in which the cover or a portion of the column contacts with the front surface. 
     
     
         17 . The shoe of  claim 11 , wherein a coverage rate of the protrusions on the shoe sole ranges from 45% to 55%, and a distance between every two adjacent protrusions is 1 mm.
