INFINITE continue to prove their undeniable popularity.

On July 3 at 8PM KST tickets for INFINITE's second world tour "INFINITE Effect" went on sale.  In ten minutes every single seat of the Seoul Olympic Park Gymnastics Stadium was sold out for both the August 8 and 9 shows. Soompi reported that roughly 330,000 fans flooded the online site to get their tickets.

The high demand for tickets did not come as a complete surprise. On June 30 ticket pre-sale went live for INFINITE's fan club, whose members flooded the server and caused it to go down. Even before either ticket sale date "INFINITE Effect" was one of the top trending searches on Korean sites.

"Thank you very much for your support for INFINITE's world tour," Woollim Entertainment responded to fans' overwhelming interest, according to OSEN. "We will be ready to work hard to show you the best performances for the concert and for INFINITE's comeback."

INFINITE's last world tour took place in 2013 where they held over 30 concerts in 10 different countries from all over the world. It addition to preparing for their second world tour, INFINITE is also gearing up for their comeback album Reality. Reality will be released on July 13.
