How many shoes does a girl really need? Naya set out to find the answer by asking its favorite eco-fashion bloggers—including Ecouterre’s own Yuka Yoneda—to assemble a week’s worth of outfits with a single pair of the label’s vegetable-tanned boots, pumps, or booties. The “Save Your Soles Style Challenge” also required each style maven to donate five pairs of old shoes to Soles for Souls to raise awareness for America Recycles Day, which is coming up on November 15. So what are you waiting for? Vote for who wore it best and you could win your very own pair of shoes from Naya’s fall line.
