As soon as I tried this shoe on, I was amazed by the fit.  I wear an 8.5 and that's exactly what it felt like.  The shoe immediately felt comfortable and I knew I'd be keeping them.  It's the first pair of shoes from Amazon (along with another Saucony vegan shoe) which have been comfortable right out of the box.  The shoe label (on the tongue of the shoe inside) says what is in it and there are no animal products whatsoever.  I will say that they seem a bit warm when worn all day and are probably not the best for walking long distances. {I mainly wear them for work, where I walk some and stand a lot.} Also, I had to get the laces fairly loose as I'm used to wearing mostly slide-on shoes (aka, Merrell breeze).
