The sole is hard as a rock and the padding that presses on the top of your foot is not flat. Great audio source for newbies, I hope this helps :) Now it all made sense. while the phone is horizontal / landscape it does not seem to fit as well as it does while vertical / portrait. They give a bit of lift too. Ive worn them three times now and theyre very comfortable. Highly disappointed in these. They are comfortable in my ears but need adjustment to stay put. this is my third pair of fit flops in a year - I am a definite convert! Works great, keeps it safe, clip function useful
