The makers of Crocs are giving away free pairs of the foam shoes all this week for "Croctober." The footwear brand is celebrating its 20th anniversary by giving away thousands of free Crocs every day until Friday to those who join the Crocs Club. Members of the free club will also be first in line to get the new limited edition Croc Day Clog, which comes out later this month. Croc Day is October 23rd.
