The regular raw edge is inlaid from the toe to the tail, making it lazy and casual, not easy to "draw", soft and not abrasive to the feet. The lining and insole are made of soft pigskin, making your feet as soft as stepping on a pillow without sagging. The classic biscuit-shaped thick bottom is improved to show the texture of bread crumbs. The rubber outsole design makes the soles wear-resistant and non-slip, and only increases height but not weight.
