Stray Kids unleashed fiery energy to kick off their new world tour “RUN IT” amid a scorching heatwave at Seoul’s KSPO Dome. Over five nights—July 25, 26, 29 and August 1–2—the eight-member group wove together tracks spanning their pre-debut days to upcoming releases, capturing their past, present and future in one seamless performance.

The show opened with “Mixtape: On Track,” followed by pre-debut anthem “Hellevator” and debut single “District 9,” symbolically turning the first pages of their story. Sweating but undeterred, the members greeted a packed arena with “Stay high!” and exchanged hellos in English, Japanese and Chinese, forging a global connection with their fans.

A highlight came when “Hellevator” received a dramatic new staging complete with towering flames and intense lighting effects. Seungmin explained, “We wanted to reinterpret our pre-debut song to show how far we’ve come, and through ‘RUN IT,’ we hope everyone enjoys both our journey so far and the road ahead.” The setlist continued as a narrative arc: fan favorites and chart-toppers led into previews of tracks from their forthcoming mini album THIS & THAT, due August 7.

Heat and enthusiasm peaked during EDM remixes of “DO IT,” “Rock,” and “KARMA,” with the group urging the crowd to “make some noise!” The collective roar from STAY—the fandom—filled the dome. Despite blistering conditions that left members nursing swollen digits and calluses, including Hyunjin’s thumb eczema and I.N’s foot blisters, the performers pressed on, driven by the audience’s fervor.

As the night drew to a close, Stray Kids treated fans to “I Do,” “After You” and early debut single “RUN IT,” then lingered onstage, lamenting the swift passage of time and joking about extending the Seoul run by a few more days. In heartfelt remarks, Hyunjin thanked fans for “making this life possible,” while Felix expressed gratitude for STAY’s unwavering support. Leader Bang Chan reflected on the tour’s title, likening their nonstop momentum to a marathon powered by the fandom’s love.

Following the Seoul finale, Stray Kids will release THIS & THAT on August 7 at 1 p.m. KST. Later this year, they will appear at Brazil’s Rock in Rio festival and headline their own StrayCity events across three Latin American cities, carrying the “RUN IT” spirit worldwide.
