Sandals are obvious style must-haves for the warmer months, and each year brings new trends to explore.

Yep, the mega-trend that invaded our closets some years ago is back in all shapes, sizes, styles and price points. From minimal leather flats, to shell-adorned details, these good-looking gladiators will pump up even the simplest summer ensemble. Take a scroll through our favorite selections below and add a pair of these to your next sunny day look.
