Until the car starts to burst into flames. Only problem is that these sandals run big so her pinky toe is squished on the side with her size 13. I just did a test run with my students and had all of them use their headphones and just like mine, everyone said that the sound came out clear and can get really loud depending on what you have the volume up. The price point was great, the thickness is fine, and they fit well - however, the sometimes slide the littlest bit. These are not a generic copy of a well known mote expensive southern based ca flight flop. Do they sound good?If you don?t like to have your eyes shake from bass, you?ll probably like these. I love volatile shoes but these run narrow and a slightly smaller than their flip flop wedge shoes. They dont have true noise cancellation like airpod pros, but at $100 less Im perfectly happy with these. Im obsessed with this tape! I read the reviews saying these were too narrow, but I have narrow feet, so figured it wouldnt be a problem.
