Amazon’s Endless.com shopping destination for shoes and accessories just got mobile.  The company announced Monday that it has launched its very own free iPhone app to allow shoppers to browse and buy on-the-go. 

The app allows users to shop according to the usual categories—women’s shoes, men’s shoes, children’s shoes, handbags, etc.—which are then broken down into sub-categories, i.e. boots, flats, athletic shoes, sandals, and so on.  For more discerning, trend-savvy shoppers, the app also includes Guest Editor Picks (favorite styles as selected by guest editors), a Fall Trend Guide, and a section for new arrivals.

Inventory includes top styles from renowned designers and fashion brands, including Dolce Vita, Pour La Victoire, Marc by Marc Jacobs, Sam Edelman, Camilla Skovgaard, Michael Kors, and Steve Madden, among others.  Users also have the option to shop by designer.  Endless.com offers two-day shipping and free returns at any point within a year of purchase.

“People are on the go more than ever and whether it’s connecting with people, working or shopping, we spend a lot of time these days on our phones,” said Shelley Salomon, president of endless.com, in a statement. “So we’re excited to be able to offer our customers the same seamless and luxurious endless.com experience no matter where they are.”

The company was built and launched by Amazon back in 2006, but Amazon was not immediately available to comment, so it is not clear how many users Endless.com currently has. Nor has the company said how many items Endless.com currently has in its inventory. 

Endless.com and its mobile app mirror the shopping experience created by Zappos, which Amazon acquired back in 2009 for $1.2 billion.  Like Endless.com, Zappos also offers free two-day shipping as well as free return shipping within a year of purchase.  Zappos launched its own iPhone and iPad apps in late 2010.

As mobile commerce continues to pick up, Amazon is making sure it’s right there on the frontlines.  Back in August, the e-commerce giant launched an iPhone app for its new fashion and home décor flash sales site, MyHabit.com.
