Practical yet pretty, flat shoes have arguably taken over heels as the new must-have. Classic ballet flats come in every shade and texture imaginable, while loafers and lace-ups offer a hit of androgynous cool. Come summer, treat your feet to the most covetable sandals, poolside-perfect flip-flops and espadrilles or why not treat yourself to a pair of luxurious slippers, ideal for adding a dose of luxury.
