The gladiator sandal has been the hallmark of summer footwear for seasons. Simple yet versatile, it's the kind of shoe that can be reinvented to suit any trend and style. The strappy ankle sandal is a timeless classic: keep it simple in plain leather or go for an embellished style, vamped up with studs or in a metallic shade for a dressier look. Or go for a more innovative design and try one of the calf-high cage styles. Rampage's selection comes in a variety of shades, while ASOS's animal-print style is the affordable answer to a high fashion shoe.
