These are Mizuno walking shoes. They do not have a zipper. Material Composition: Artificial Leather Sole Material: Synthetic Sole Outer Material: Faux Leather Closure Type: Lace-up Country of Origin: Vietnam About this product: Sole thickness: 2cm Product Description: The new artificial leather type of LD40 is here. Recommended for those who prefer not to have a zipper! I've used these a few times, but they still seem wearable, so I'm putting them up for sale. I have disinfected them overall, but if you are concerned, please disinfect them again before use.
