I will definitely be a returning customer. Theyre cute, fun, and feel just great after walking around shopping for a few hours. These are great sandals at a great value. Oversized bottles will likely not fit. The microphone never worked after trying on multiple devices so they are going to the trash bin. The sandals fit great and are so cute but ya they are not durable at all. Instantly connects, I LOVE the ambient mode when I’m outside gardening or on a walk and still want to hear some outside noise. My foot size is 8 and I purchased a 9 and it was narrow at the top. One of the towels are less fluffy than the other & neither fit. The sounds is great so far and it connects to my phone with no problem.
