I call it kicky boxing. Kickboxing sounds so aggressive. ive been doing, like, kicky boxing." Brand also said. "But it's not like I kicked someone so hard that a bit of my foot fell off. Its that there was abrasiveness caused by the foot pad. Its essentially a rug burn." Russel has not been wearing shoes do to his injury he states "I mean, shoes are, in themselves, an oddity and addition." It doesnt sound like his injury is very serious, though if it were me I would wear shoes, especially while doing activities outside.
