San Francisco-based sneaker startup Allbirds opens its first D.C. location Thursday with a Georgetown store that will feature a limited-edition, D.C.-centric pair of shoes. The 1,902-square-foot store at 3155 M St. NW is Allbirds' ninth brick-and-mortar location in the United States, as the company has pivoted from an online-only model, following in the path of several e-tailers that felt a physical location was key to further growth.
