I'm gonna say no purely from a commercial standponit. Look at a mall map for example. It's broken down into: Mens Apparel, Ladies apparel, Childrens Apparel, Shoes, and depending on the size of your mall accessories (such as handbags, baby equipment and jewellery).
If you look at it from a big box store perspective, such as Wal-Mart or Target, shoes are located in a completely seperate area away from their core fashion. Mens shoes are never in the mens department for example. Also promotionally, if Target were to have a sale on apparel, such as 25% off all summer fashion, it would never include footwear unless it was explicitly stated.
