Online footwear retailer Shoes.com, a subsidiary of Brown Shoe, is revamping its Web site as part of an ongoing initiative to enhance the cus­tomer experience on the site. After a one-year partnership with Bazaarvoice, Shoes.com is now tapping into user-generated potential by using Bazaarvoice's Ask & Answer tool, a social commerce service that lets shop­pers post and respond to specific prod­uct questions on e-commerce sites.
