“The sandals are made from durable, colorfast polypropylene rope. Water does not hurt them because they are melted together instead of glued. They have excellent traction when wet, and they are machine washable. They last for several years. We guarantee the sandals for a year, and many customers are able to wear theirs for many years. They are lightweight, cool, and they bend easily. The ropes are soft and comfortable on your feet, and the heel-strap holds them on securely.” A full range of sizes and colors for men and women.
