If your looking for rubber flip flops and want them to last then you need to buy Havaianas.  The price may seem a little high as compared to what you find at the local mall but they are worth the price.  They are very comfortable and will last much longer than a pair that cost a couple of dollars.  I own many pair and have never had a pair break and the designs have never worn off the footbed like cheaper sandals.  You will not be disappointed if you buy these.
