I wore these shoes for the first time a few days ago. They are definitely not leather. They aren't high quality shoes. The tongue says made in China and doesn't say what the material is but it feels and looks like cheap vinyl or man made. The laces are very light weight and the fabric that makes the tongue is also very light. I don't expect them to last long, but I am not normally hard on shoes. Ideally I wear a 6 extra wide but that size is rare. Orthoheels Vionic doesn't make them. So I ordered  6 1/2 Wide. It fit comfortably. There is plenty of room in the toe, and my heel didn't slip. I had minimal pressure on the side of my toes, but wore them for several hours without problems. The biggest advantage to these shoes is the aggressive Orthoheel arch support. It really relieves the ache of plantar faciitis. For the price, they are fine with no extra orthotic insert required. Edit 8/6/15 Correspondence with seller regarding the fact that they are described as leather was not satisfactory. The seller claimed the description was &#34;leather and manmade upper&#34; but I definitely don't read that and I can't see anywhere on the shoe that looks like leather. I decreased my rating by one star for this. I am not interested in returning the shoes. I will not buy from this seller again. I tried to find my feedback to reflect this and it's gone with no way to leave seller feedback or edit it. Seller name Peltz.
