For the second time in two weeks, major footwear brands are growing by acquisition. Caleres, a portfolio of global footwear brands including Famous Footwear, Sam Edelman and Diane Von Furstenberg, has acquired Vionic Group, a maker of supportive footwear and orthotic shoe inserts, for $360 million. Earlier this month, footwear giant DSW partnered with Authentic Brands to acquire Camuto Group for $375 million. The move is designed to further expand Caleres' stable of shoe brands and give the company "additional access to the growing contemporary comfort footwear category," according to a company statement. Vionic has generated approximately 25% of its total sales online over the past 12 months, indicating that the orthotics manufacturer could give Caleres a strong disruptor to power its digital strategies going forward.

Just a few weeksafter Walmart acquired Eloquii, a plus-sized fashion retailer, the retail giant has reeled in its next digitally native brand. Walmart acquired Bare Necessities, an e-Commerce intimates and sleepwear retailer, for an undisclosed sum. Walmart has prioritized fashion as a core element of its e-Commerce experience, ever since overhauling Walmart.com in May and introducing the Lord & Taylor flagship e-Commerce site. These changes, as well as the company’s continued spree of acquisitions, starting with Jet.com in 2016, are designed to give Walmart access to younger Millennial customers who do not normally shop on its web site. The company also partnered with comedian and talk show host Ellen DeGeneres to launch a women's fashion line in August.
