Circa (styled as C1RCA) is a skateboard footwear and apparel company founded in 1999 that is based in San Clemente, California.

Adidas and BAIT released a collaboration in spring 2016 for 4/20, the Stan Smith Vulc "Happy", which included a hemp upper and a weed stash spot in the tongue.

When asked why he left to start Black Box Distribution in 2000 and later Fallen Footwear in 2003, he said "I left Circa because we were supposed to launch a new sister footwear brand based on the momentum of my line, but they had some massive issues with their snowboard brands, which put them in a serious cash crunch.

"[6] When asked whether he still had an ownership stake in the company, he said "Yeah, as crazy as that is; when I left to start Fallen my stock was fully vested and they weren’t in the position to buy me out, so it’s just been there chillin.

"[6] A milestone for the company was the release of "It's Time" in 2006, an almost 43 minute long skate video filmed in the United States with skaters Adrian Lopez, Colt Cannon, Dennis Durant, Jon Allie, Peter Ramondetta, Sierra Fellers, Tony Tave, Windsor James and Nate Sherwood.
