The invention discloses a front-and-back breathable leather shoe. 2-4 first openings are formed in the front portion of an upper (1) from front to back, each first opening is provided with a first rubber belt (4) matched with the first opening in shape and size, and ventilation holes with the same aperture are densely distributed in the first rubber belts (4). The middle of the back end of the upper (1) is provided with a second rubber belt (41), the second rubber belt (41) is formed by overlapping a second outer layer rubber belt body (41a) and a second inner layer rubber belt body (41b), and ventilation holes are densely distributed in the second outer layer rubber belt body (41a) and the second inner layer rubber belt body (41b). Due to the fact that the rubber belts with the ventilation holes are arranged on the front portion and the middle of the back end of the upper of the leather shoe, the breathable function of the leather shoe can be effectively enhanced, the foot and the leather shoe can be prevented from being affected with damp, and the breeding of bacteria is avoided.

The invention discloses a front-and-back breathable leather shoe for a man. A plurality of first rubber belts (4) are arranged on the front portion of a first upper (1) from front to back, each first rubber belt (4) is formed by a first outer layer rubber belt (4a) and a first inner layer rubber belt (4b) in an overlapping mode, and air holes are densely distributed in the first outer layer rubber belts (4a) and the first inner layer rubber belts (4b); a second opening is formed in the middle of the rear end of the first upper (1), a second rubber belt (41) which is matched with the second opening in shape and size is arranged on the second opening, air holes are densely distributed in the second rubber belt (41), and the calibers of the air holes are equal. According to the front-and-back breathable leather shoe for the man, due to the fact that the breathability function of the front-and-back breathable leather shoe can be effectively improved, a foot and the leather shoe can be prevented from being affected with damp, and bacterium breeding is avoided; the front-and-back breathable leather shoe for the man has the advantages of being ingenious in conception, simple in structure, easy to modify, low in cost and the like.

The invention discloses a pair of ventilation leather shoes for men. A plurality of first rubber belts (4) are arranged at the front part of a shoe upper (1), the first rubber belts (4) are formed by sequentially overlapping a first outer layer rubber belt (4a), a first middle layer rubber belt (4b) and a first inner layer rubber belt (4c), vent holes with the same hole diameters are densely distributed in the first outer layer rubber belt (4a), the first middle layer rubber belt (4b) and the first inner layer rubber belt (4c), two second rubber belts (41) are respectively arranged at the left side and the right side of the back part of the shoe upper (1), the second rubber belts (4) are formed by sequentially overlapping a second outer layer rubber belt (41a) and a second inner layer rubber belt (41b), and vent holes are respectively and densely distributed in the second outer layer rubber belt (41a) and the second inner layer rubber belt (41b). The ventilation leather shoes have the advantages that the ventilation performance of the leather shoes can be effectively enhanced, the dampness of the feet and the leather shoes can be prevented, and the germ propagation is avoided.

The invention discloses a breathable cross ventilation leather shoe easy to wear. A transverse opening and a longitudinal opening are formed in the front portion of an upper (1), a transverse rubber belt (4) matched with the transverse opening in shape and size is arranged in the transverse opening, a longitudinal rubber belt (5) matched with the longitudinal opening in shape and size is arranged in the longitudinal opening, the transverse rubber belt (4) and the longitudinal rubber belt (5) are crossed and are of double-layer net structures, the left side and the right side of the rear portion of the upper (1) are respectively provided with a first rubber belt (8), a second rubber belt (9) is arranged in the middle of the rear end of the upper (1), the first rubber belts (8) and the second rubber belt (9) are of double-layer net structures with diamond-shaped meshes, the outer-layer meshes of the first rubber belts and the inner-layer meshes of the first rubber belts are staggered, and the outer-layer meshes of the second rubber belts and the inner-layer meshes of the second rubber belts are staggered. Accordingly, breathability of the leather shoe can be improved, so that the foot and the leather shoe are prevented from being affected with damp, and breeding of bacteria is avoided.

The invention discloses a dampproof leather shoe easy to wear. A plurality of first rubber belts (4) are arranged at the front portion of a shoe upper (1) from front to back. Air holes are densely distributed in the first rubber belt of each layer. The left side and the right side of the rear portion of the shoe upper (1) are respectively provided with a second rubber belt (41). Air holes are densely distributed in each second outer layer rubber belt (41a) and each second inner layer rubber belt (41b). A third rubber belt (42) is arranged in the middle of the rear end of the shoe upper (1) and formed by overlapping a third outer layer rubber belt (42a) and a third inner layer rubber belt (42b). Air holes are densely distributed in the third outer layer rubber belt (42a) and the third inner layer rubber belt (42b). According to the dampproof leather shoe easy to wear, the breathability of the leather shoe is enhanced effectively, feet and the leather shoe are prevented from being affected with damp, and bacterium growth is avoided.

The invention discloses a ventilating breathable leather shoe for a man. Two to four first rubber belts (4) are arranged on the front portion of an upper (1) from front to back, each first rubber belt (4) is formed by a first outer layer rubber belt (4a), a first middle layer rubber belt (4b) and a first inner layer rubber belt (4c) in an overlapping mode, and air holes are densely distributed in each first layer of each first rubber belt; the left side and the right side of the rear portion of the upper (1) are respectively provided with a second rubber belt (41), air holes are densely distributed in the second rubber belts (41), and the diameters of the air holes are equal; a third rubber belt (42) is arranged in the middle of the rear end of the upper (1), air holes are densely distributed in the third rubber belt (42), and the diameters of the air holes are equal. According to the ventilating breathable leather shoe for the man, due to the fact that the rubber belts with the air holes are arranged on the front portion of the upper, the breathability function of the ventilating breathable leather shoe can be effectively improved, the foot and the leather shoe can be prevented from being affected with damp, and bacterium breeding is avoided.
