For spring '15, the racier the lacing, the better. Fine multi-strap detailing lent runway footwear sinewy appeal. At Givenchy, Altuzarra and Alexander McQueen, the look swung decidedly more vixenish via stiletto heels. For a different spin, Chloe, Valentino and Band of Outsiders kept the look more gladiatorial with flat-soled sandal shapes, another key trend for the season.
