I have 2 pairs of their Canvas Sandals which led me to buy the Canvas Slide. He solved the problem easily by cutting the two elastic stretch areas on each side of the tongue. If I place the phone and it’s off by a cm or so it won’t charge. I bought these from a reseller and they were new but looked like the box was opened. I am very satisfied with the item, would recommend to others. This design is very clever. While standing, there was still about 3/16" between support and my arch (hard to tell in pic, sorry for ugly foot). Speaking of outdoors, the little tree button on the bottom does make a noticeable difference in the sound when pressed. Purchased as a gift! I guess if I never had any headphones before and used the Amazon headphones, I would probably just accept it because I had nothing to compare it to.
