I can usually figure things out and dont really care about the instructions, but in this case you have to "dial" the front of the suction cups to set them! Rough & Tough! Love the wide toe box. QUesto modello in particolare ha una suola anatomicha che le rende ancora più comode. Much more comfortable than any others that I have tried and the fact that they are sturdy and lasted so long is amazing. The toe sticks out a little more because of it, but I have not found it at all uncomfortable or sloppy like you would when you wear shoes that are too large for you. They are super comfy, but just too big. It would be an easy enough fix to apply a bit of glue (tape would probably cause the upper case to ill-fit the Air Pod case lid, as its so precisely molded) but that would defeat the point of having a cool case around my otherwise pristine Air Pod case. I suppose theyll serve their purpose and you cant argue with the price, but they are not going to last beyond this summer if they even last that long. The shape and color of finish are nice, but I bought three sets and all six ends have a scuff around the ball from machining that doesnt buff all the way out.
