Gurkee's Neptune Yellow Sandals Gurkee’s rope sandals are hand crafted from extra soft polypropylene rope, that is saltwater resistant, chlorine resistant and machine washable. Polypropylene rope is the same material from which carpet fibers are made, that is why Gurkee's last so long, feel so soft and are light on your feet. The double layer, industrial strength outsole of the Gurkee’s sandal offers flexibility with every step, yet is durable enough to last for years. This is an experience that will truly take you beyond bare foot!
