I have had similar shoes for years, and always have trouble finding them when my current pair get worn out.  I bought the 7W - I am usually somewhere between a 6.5 and 7, and can go regular or wide.  These are just a tiny bit to big, but I don't think big enough to warrant a smaller size.  Also, they are a bit slippery on the bottom, but that might just be the "new" in them.
