Bam! Pow! Wow! Footwear designers went for graphic pops of color and Warhol-esque prints for spring ’12, offering up a plethora of shoes that would suit chic superheroes in modern-day comic books. From Pierre Hardy’s painted python sandals with metal overlay to Nicholas Kirkwood’s raffia and patent booties at Pollini (and lots of stripes, dots and clever cutouts in between), the trend offers fun, eye-catching spring styles.
