When it comes to comfort and style, Crocs Unisex-Adult Classic Clogs (Best Sellers) 13 Women/11 Men White are a solid choice. They offer up simple slip on convenience, secure fit from the pivot heel straps, lightweight design and durable construction that can take whatever you throw at them. Plus they make all the ladies look good too, so there's always that. In terms of size it varies by individual but if you're between sizes I'd suggest going for the next largest whole size down as these are designed with a roomy fit in mind. Wherever you wear them or whatever you do in 'em just be sure to clean up after yourself and use soap & water or else your crocs will get stinky faster than your bros eating off your last bong hit!
