I have the other 3 grand slam shoes that Asics produced, but they came in women's sizes. Calling these unisex shoes just means that they are cut for men's feet. I carefully purchased the correct size, but the toe box is too big in width as well as slightly longer which makes the shoe feel awkward during play. If I went down a size the arch of my foot which is high would have never fit in the shoe. I love Asics and have been buying them for many years, just disappointed they went for this short cut on such an expensive shoe.
