Macbeth Brighton in gray are the most versatile casual shoe I own. They look really good with shorts, pants, and are comfortable as heck. I also love the toe, very neutral which makes it look good at any angle.
If you're size 10.5, these are the cheapest you will find. This is my ebay, but this isn't shameless advertising. I own about 40 pairs of casual shoes. I've been wearing these all summer. I bought that size too big.
