5SOS Promise That Their Tour Will Be Something Fans Will Want To See 'For Years To Come’

Even if they didn't think it would 'ever happen.'

In a little over one month, the 5SOS fam will be rocking out with their socks out.

5SOS hit the road on May 4 for their very first headlining tour, which will take them all over the world in support of their self-titled album.

"It's our first headline arena tour which is awesome and I didn't think would ever happen," Luke told us at the iHeart Radio Music Awards before Michael added. "I feel like it was just yesterday that we were playing to like 300 people. It's going to be awesome."

The band has been very involved in the development process of the Rock Out With Your Socks Out Tour, which features Hey Violet, the first signee to their Hi or Hey Records, as an opening act.

"The process of putting together an arena show is really amazing and we get really involved in the set and how we want the show to be and stuff like that," Calum said. "So it's an amazing process.

So any big surprises for the show? Not sure if they've gotten that far since it seems that they are having a hard time believing the fact that they are actually putting on an arena tour.

"I think it's a surprise that we actually made it to a level where we could tour around the world," Ashton said. "That's pretty cool to us and hopefully to the fans as well. We just want to make a show that they are going to want to come back and see for years to come 'cause we want to do this for as long as we can. We love it."
