Allbirds sells footwear for men and women made from comfortable merino wool. These simple wool shoes minimize odor, regulate temperature and wick moisture for a cozy fit all day long. Products include wool runners for men and women as well as replacement insoles for the shoes. New products are in the works for the future. Purchases can be made at Allbirds.com or at their San Francisco pop-up store from Sept. 7 to Jan. 31.
