Wellington entrepreneur Jeremy Bank was was inspired to create sustainable shoes after his daughter found plastic all over what had been a pristine beach in Hawai'i.
Last year he crowd-sourced $80,000 to get his company YY Nation to the next stage.
Yesterday, the company launched its first range of four styles of shoes in the United States - made of merino, discarded pineapple husks, algae, bamboo and recycled plastic.
