I bought 12 wide and wore them for 1 week. Internal arch support was good for the first 3 days but wore out quickly. I thought I needed to break my shoes in a bit more and unfortunately after 1 week I found that they were becoming too uncomfortable - I had to buy a new pair of shoes in the middle of a walk. I compared the outsoles of shoes from different brands and found that the outsoles were smaller (shorter and not as wide) than the 3 other brands I compared them to.
