Crocs is offering medical personnel in the U.S. battling the Covid-19 pandemic a free pair of Crocs, shipping included. The American company began gearing up in late March to dispatch up to 10,000 pairs a day in response to online requests. In addition, Crocs plans to donate up to 100,000 pairs to select hospitals and clinics. The initiative will continue for as long as inventory permits and is drawing on the cooperation of such retailers as Shoe Carnival, Famous Footwear and Rack Room Shoes.
