Hari Mari's Dunes II Flip Flops are made from a special kind of foam, soft-squeeze foam that is more cushion-able than regular foam. In addition to being softer, the foam is also aqua friendly meaning they will float on the water with ease. Like other Hari Mari Flip Flops, these flops feature Memory Foam Toe™ which gives the flip flops no need for a break in period. The non-marking and carbon free soles are boat safe and perfect for spring and summer weather. Hari Mari's carbon free footbed siping channels water away and grips feet with ease, while providing additional comfort. The footbed also features odor eliminating anti-microbial foam that ensures these flip flops will not become smelly like some other flip flops might. Additionally, the footbed contains a firm arch support that makes these flip flops perfect for all day wear. The Dunes II Flip Flops by Hari Mari are lightweight, comfortable and ideal for use all spring and summer long.
