The invention provides an air mesh cloth with tapered meshes. The air mesh cloth comprises a surface layer, a bottom layer and a middle layer used for connecting the surface layer and the bottom layer. The surface layer is provided with first meshes uniformly. The bottom layer is uniformly provided with a plurality of second meshes arranged at the same axis of the first meshes. The cross section area of the first meshes is bigger than the cross section area of the second meshes. The middle layer has a cavity between the first meshes and the second meshes. The invention also provides a manufacturing method of the air mesh cloth. The air mesh cloth is capable of forming tapered meshes between the first meshes and the second meshes. The external air of shoes flows from the second meshes to the tapered meshes and fast spreads into shoes when the air volume is enlarged. The internal hot air of shoes flows the first mesh to the tapered meshes under the actuation of impulsion generated by shoes movement. When flowing through the second meshes, the air is compressed to release thermal energy; thus, the air exchanging effects and the heat exchanging effects are relatively good.
