Every once in a while in fashion a trend arises that's absolutely polarizing. The perfect example? Birkenstock style sandals. People seem to either love or hate them. Personally I've never had a strong stand on the hippie shoes, but after seeing them worn by some of my fashion icons, the style is growing on me. Amy Astley, Teen Vogue's Editor-in-Chief, recently posted a couple of images of her sandal-clad feet on Instagram. The thick-strapped shoes looked super fresh in white and also very comfy. I may have to treat myself to a pair!
