Rapper Big Boi is turning his love for a good pair of socks into a profitable business idea by launching his own collection.

The Outkast star has been trying out his new Left Foot products for himself and he is excited to share the Crooks & Castles design collaboration with fans.

The Atlanta, Georgia native tells the Wall Street Journal, "They will be very colourful, you know. Some have images of pitbulls on them, also some with gold chains and medallions. A lot of different designs and very, very colourful. It reflects my personality. I can't wait for people to get them. I've been rocking (the socks) for a few weeks now, the samples. They're comfy."

And Big Boi insists his sock fetish is nothing new: "One of my passions has always been flip flops and socks. That's what we do down here in the South...

"If you go back a few years, me and (Outkast bandmate) Andre 3000 always be into socks, and such (sic). It's just part of your whole get up, part of your whole outfit. I just want to bring a fresh layer to it."
