These Calvin Klein flat slides are seriously gorgeous and make you feel good about what you're wearing. The woven design gives them this really cool, textured look that goes with pretty much everything. What's awesome is they're made with recycled materials – the straps and lining use recycled faux leather, and even the insole is made from recycled foam. So you're looking great while actually doing something good for the planet. They've got this subtle little heel (like barely there at 0.2 inches) and a trendy square toe that keeps things modern and comfortable. The Calvin Klein logo is embossed on the heel, which adds that perfect designer touch without being too flashy. If you care about style AND sustainability, these black sandals are basically made for you.
