Whenever I find myself in need of new shoes these days, I find myself continually purchasing them from DSW. They have really great prices.
As someone with a large wide foot, I am able to find a lot of shoes for myself here despite that. They have tons of sneakers for me, as well as a decent selection of dress shoes.
Their clearance section is also helpful, as they sort the shoes by size. Also, even though the discount prices are not stated directly on the shoe, they have a handy price sheet on each rack to help figure out the percentages.
