New craze of wool shoes in San Francisco

SAN FRANCISCO, Ca. (WPVI) -- There's a new shoe craze in the San Francisco area.

This footwear is made almost entirely out of wool.

They're called "All Birds".

They are the brain child of Joey Zwillinger, and Tim Brown who hails from New Zealand, where this isn't such an odd idea.

" Everyone in New Zealand knows that wool wicks moisture, regulates temperature, does all these amazing things for free. And hopefully we're

helping to educate America a little about the magic of wool too," said Brown.

Those who have purchased them say they are very comfortable, keep cool, and are considered work casual.
