They look pretty much like other shoes- they're just made with imitation leather or fabric. They don't hold up as well as leather shoes, though- and many times they (at least the fake leather ones) don't breathe well so your feet get sweaty.
I had to look them up also and they look nice but maybe a little pricey. You can't actually call them true " Vegan " shoes as they do use other by-products to make them. Read this info and you'll see what I mean.
