Though "Zilch meets Zirra" may sound like a Japanese monster movie, it's actually a happy marriage of two our most popular sandals. You get Zilch's sport and travel aptitude with Zirra's thin straps and stylish attitude - and everybody wins. Zirra Lites's minimalist footbed and sole provide extraordinary comfort, flex and grip. Plus you can roll, stuff and jam them flat in a bag or backpack for easy travel. Our Spider Original rubber is made to grip like crazy in wet environments. Open toe construction doesn't allow water to pool. An adjustable ankle strap makes for a good fit. Hook and loop strap lets you skip the laces. A microfiber footbed is soft and luxurious. A minimal upper design gives you all you need and nothing more. Synthetic upper.
