Thank you for viewing. This is a bowling shoe cover. Size: M (up to 25cm) It has a lining and the sole uses synthetic leather. Bowling shoes can cause unexpected injuries such as falls if they get wet. Why not use an original cover? I am an amateur at sewing, so there may be some roughness in the seams and slight irregularities in the shape. Please understand this. The fabric pattern can be used for commercial purposes (sale). Also, the shoe cover itself is not waterproof.
