Gwen Stefani Breaks Into Upper Echelon

Gwen Stefani looks as fashionable as ever as she takes her adorable sons Kingston, 3, and Zuma, 15 months, for a walk through London on Tuesday (December 22).

The 40-year-old No Doubt frontwoman killed it in a killer pair of studded Upper Echelon shoes, which were created and designed by New York City natives and best friends, Seth Campbell and Nick Cohen. With respective family backgrounds in the footwear and jewelry industries, the duo created a concept they have coined “Shoewelry.”
