Allbirds shoes made of wool a hit in tech world

SAN FRANCISCO (KGO) -- The latest trend in the tech world isn't on your screen, it's on your feet.

Joey Zwillinger helped invent shoes called Allbirds with co-founder Tim Brown who is from New Zealand.

The shoes are made almost entirely of wool.

After becoming an overnight hit in the technology world, it only makes sense the shoes have attracted a lot of attention from venture capitalists.

After taking on $2 million in August, Allbirds just closed another $7 million in funding in time for the holidays.
