I used to wear Adidas ZX, then tried their Gazelle, also Flux… Frankly speaking they all are comfortable, but each one has its pros and cons. I decided to try smth. more intresting and ordered a pair of Venzo Shimano SPD Shoes. Just in case you haven't heard about them:
At first blush they looked a bit tough, though I have found them in white colour and was very satisfied. Real bike cycling shoes, quick-drying, highly breathable unlike Adidas ZX, which I had to dry for several days! IMHO they are cool, you should also try…maybe not this very model, but something similar.
