The gladiator sandal craze started in the summer of 2008 and we’re going to see it continue into 2015. Crafted after the footwear worn by Roman gladiators, the strappy footwear has become a seasonal must-have. Valentino’s “Rockstud” high heel gladiator sandal ($1,145) features the brand’s iconic studs and is crafted from soft calf leather. The 4-inch chunky heel adds feminine allure. Be bold. Be a gladiator.
