If you've been paying attention to new designer releases for spring summer 2014, you'll notice a trend emerging with footwear. For those of us who lived through the 90's you'll remember the worldwide craze for Birkenstocks. You'll also probably remember your mother telling you to hang on to everything you buy as trends are cyclical. Well, now I'm wishing I had hung on to my vast collection of Birkenstocks from my teens as the designers are saying these bad boys are cool again. Only these aren't you're average Birkenstocks. No, this is the way Giambattista Valli, Marni, Isabel Marant and Givenchy translate the trend. They also come with some rather astronomical price tags, ranging from £280 to £585. Yowsers. For any of you DIY bloggers out there, we'd love to see how you jazz up a pair of old Birks to meet the new trends.
