Wear of the shoe sole is intense. About one month in use The fine pattern of the sole is about half disappeared. Also, the black reinforcement part of the heel and the like also come off. Because I am anxious, I use insole to prevent stepping out.
After use, the black part of the shoe sole peeled off in about a month. Since the sole of the shoe is filled with urethane, I think that it is good because the water does not come into contact even if the heel wears out.
