Buena calidad, me gustó bastante y luce muy bien en el baño Cords knots like a fish net and they keeps falling out of your ear. I bought the xxl & they fit wonderfully. Easy install with 4 screws each section that were included. When I adjust either the top strap or the rear (heel) strap to a barely snug fit, the strap sticks out from the shoe about an inch or more. I can’t speak to durability (from experience) yet, but the double stitching in high stress areas tells me they were thoughtfully designed. I got them to wear in the house on ceramic tile floors. Im a Floridian, an expert in flip flops, and Ive bought Havaianas for years - no more! The space on both the shelves and inside the bottom cabinet are so tiny it makes me question if they photoshopped those cleaning products in the image. After all these may seem expensive but if they can keep them in your ears its cheaper than a new pair of Aiprods!
