Beware. If my product is a representative of the production chain. The very low price of these sandals screams what I find: the Vietnamese sandal manufacturer doesn't seem to know that the quality of the stitching of the Velcro on the straps is critical. Poor stitching means the straps have trouble moving through their loop attachments. So this is indeed a terrible fatal flaw for this product. I can't imagine it lasting very long. Have you heard of tight tolerances? It's the opposite of that.
