Allbirds is an American-New Zealander company that offers specialized casual shoes with uppers made of eucalyptus fibers, wool, or a eucalyptus and wool blend. Even the inner soles are environmentally friendly, constructed of a special foam made from the oils of Brazilian sugar cane. Because of this unique construction, special washing methods are required. Most can be machine-washed with one exception. If you do not have a washing machine, all types of Allbirds can be hand-washed in a sink or large plastic tub. All shoes must air-dry before wear.
