【KAZEN KAZEN】KZN187-50 Medical Shoes Color: White Size: 22.5cm I wore these for about six months while doing office work. The KAZEN logo on the insole is half gone. They have air cushioning and are very comfortable to wear. I washed and stored them, so there is no odor. There is some dirt, but there are no tears, and I think they can still be worn sufficiently, so please consider using them if you'd like. They are easy to put on and take off, so I think they are also suitable for nursing care.
