Flips flops are a summer favorite for footwear, despite the fact that they can be kind of flimsy. Straps will rip out of the base of the shoe many times, causing chaos for those away from home. Interchangeable Flip Flops uses a unique “boomerang” design that makes straps more secure. In addition, they come with extra straps in different colors, making the shoe more versatile and fun. For anyone whose ever broken a flip flop, this Australian product seems well worth it. Backers can donate $25AUD for one pair of shoes and a pair of extra straps. It seems a small premium for a a bit more reliability and style options although for the summery shoe wearer. Interchangeable Flip Flops hopes to raise $30,000 on Indiegogo.
