B2 Mid Cut Canvas Sneakers

The sole of the shoe has a double structure with eight air holes on each side, four on each side, and grooves on the back of the insole to allow air to enter. The insole is designed to allow air to enter through the grooves on the back of the insole, making it highly breathable and less likely to become uncomfortable even when worn barefoot. The cushioned insole can be easily removed and the sneakers can be washed without removing the insole. The invention of the "NATURAL PERMANENT VENTILATION SYSTEM" with its eight air holes on the sides has been patented worldwide, and is easily recognizable as SPRING COURT on the outside.
