Crocs is giving away pairs of its trademark foamed clogs to tens of thousands of people with its "Croctober" event to celebrate its 20-year anniversary.

For a chance to receive a free pair of Crocs visit the Crocs website and enter where it says "Croctober 20 Free Pair For All." The event started earlier this week, but will be going on from Oct. 1-7 and you must enter between 10 a.m. and 3 p.m. ET.

"We're kicking off #Croctober with free Crocs for our fans! (Or if you're not a fan, are you tempted enough join the Croc side?," Crocs said in announcing Croctober on Saturday.

The Colorado-based company insists that fans enter everyday for a higher chance of receiving a free pair.

Crocs has done giveaways in the past, as it provided their clogs to healthcare workers in May for National Nurses Week.

At the time, it partnered with healthcare lifestyle brand FIGS to give away 10,000 pairs of Crocs shoes in addition to 10,000 pairs of scrubs to caregivers in the U.S.

Crocs has also seen a major increase in popularity over the past few years, with the company reporting a major increase in sales in 2021.

In January, Crocs reported a 67% overall climb in sales in 2021 from 2020.
