The words "fashionable" and "comfortable" don't often go together when it comes to the latest trends. But this season, celebrities, fashion bloggers and designers alike are hitting the streets (and the runways) in a '90s (and '70s) throwback -- Birkenstocks. And whether you're on board with the whole "normcore" trend or not, everyone can agree these slide-on sandals make appearing trendy pretty effortless.

Style mavens are pairing basic Birkenstocks with slouchy separates like boyfriend jeans and oversized blazers, or mixing it up with Fashion Week's quirkier colorful and studded pairs. No matter how you wear them, one thing can be agreed upon -- no more blisters for you.

Fashion is cyclical, but Susie Lau (the Brit blogger behind Style Bubble) proves you can still put a new twist on an old favorite. Her purple Birkenstocks are a fun update paired with equally colorful coordinates.

Jessica Alba, or as we like to call her, "Queen of the Boyfriend Jeans," pairs denim blue Birkenstock sandals with an airy top and slouchy jeans for an off-duty weekend look.

The Man Repeller's Leandra Medine's white Birkenstocks appear professional and polished, while still retaining their laidback appeal, when worn as part of a monochromatic ensemble. Stick to tailored pieces in classic colors for this more dressed-up look.

The appeal of Birkenstocks rests in comfort -- and a little quirk. Fashion blogger Style Limelight embraces both with her high-fashion take on the tomboy look. An oversized blazer and sports jersey, plus basic black Birks and total bedhead equals perfection.
