On 21 May 2008, the band embarked on a headline tour to promote "Smart Casual" which finished with a performance at Astoria 2 on 5 June 2008. The support for the tour was provided by American punk rock band Valencia. This was followed by another headline tour during October, with support provided by This City and Save Your Breath, and a European tour with Zebrahead and Simple Plan. The band were one of the support acts for Paramore and New Found Glory on the 2008 RIOT Tour – during which guitarist Iain Mahanty joined New Found Glory onstage to perform their song, "Hit Or Miss". They also supported Fall Out Boy on their UK arena tour in March 2009.
