I got totally confused by the instructions and thought Id got the wrong set. My right foot is the one that hurts and the whole time I wore the shoes (2 hours) my foot hurt terribly. Maybe okay for "visual learners", but Im an old guy who prefers clearly written instructions. But, this CNX is SMALL and minimalist. The top of the case cover always falls off when opening the AirPods case, sometimes even when I don’t open them. I’ll give it , I have a small torso area so maybe this may not happen for everyone but it does for me. My hubbys size 14 crocs are on the bottom shelf for reference. On the 3 the buttons were indented on the four there is something on top of the fabric to press these buttons. as well. It is a modest machine but that is what the mini is all about.
