[4] Koston co-owns both Fourstar Clothing (with Guy Mariano)[5] and the skatepark/website "The Berrics" (with professional skateboarder Steve Berra).

[6][7] Eric Koston was born in Thailand, in the same hospital as fellow professional skateboarder Alphonzo Rawls (a shoe designer as of 2011).

[12] Following H-Street, in 1992, Koston joined 101 (a division of World Industries headed by Natas Kaupas) and in 1993 the Girl team and appeared in the videos Goldfish, Mouse, Yeah Right, and Pretty Sweet.

[17] Following his departure from éS, Koston joined the Lakai roster and a video was published onto YouTube to announce the move.

Koston's eventual departure for a place on the Nike SB team was accompanied by a YouTube video that parodied the George W. Bush shoe-throwing incident.

It's completely different, I hate to say it, but it's so much better because of what…not only in the design aspect and the resources…cos I've copied so many Nike shoes, you know, I tried to mimic them as close as possible and using the best those companies, éS and Lakai could do.

Eric took inspiration for these shoes from his more mellow family life now in his late 40's, with Nike stating "the Koston Blazer reflects his newfound passion for beachside time surfing with the fam.

"[27] As a sponsored rider for the Oakley sunglasses brand, Koston completed the "Fear and Loathing in Australia" video project that was filmed in early 2013.

Accompanied by teammates, Rune Glifberg, Ryan Sheckler, and Curren Caples, Koston appears in a video that was published on June 5, 2013[28] and photographs that were shot by professional skateboarder Arto Saari.

[6] On Friday, February 20, 2015, he did a promotional spot on his Instagram account for the McDonald's Corporation, making him among the first popular professional skateboarders to advertise for the mega-chain.

Koston has stated in an interview that he will be riding Skate Mental and WKND boards while he and Guy Mariano work on their unnamed company.

[38] In August 2024, Koston joined EDGLRD's skateboarding team founded by Harmony Korine and led by Sean Pablo.
