SALOMONWomen's Ultra 3 GTX Low Rise Hiking Shoes

I usually wear a 5 or a 5.5 in an athletic shoe. Does this shoe ran large? It was suggested I order a 5.

Is this shoe waterproof?

Do these come in wide size?

Is the x-ultra-w mean wide? and if that's the case why do so many reviews say this if for narrow feet?
