Mizuno Futsal Shoes LANCAMENTO WAVE PRO 5 ● Materials: Upper / Natural leather (washable kangaroo), artificial leather, synthetic fiber; Sole: Synthetic resin, rubber ● Features kangaroo leather that molds to your feet with every wear. ● The outsole uses non-marking rubber across the entire surface, which won't stain the gym floor. I bought these a few years ago and used them for about six months. I used them for about two hours once a week. I've been storing them at home for about a year. There are some scratches and dirt, but I think they are still usable. Feel free to comment.
