These crocs are so comfortable I haven?t taken them off around the house since they arrived! Ever since I took a cruise through the Caribbean three years ago my skin has been different. I had to screw them to the door to get them to work. Im very happy I finally found a happy medium - had to sacrifice a nespresso pod to test the texture! I wear a 7 and bought the 7 1/2 instead based on a couple of reviews that said they were happy they sized up. Can?t really see what?s inside I rarely use the armhole snap though bc my hands stay in my jacket pockets clutching Hot Hand hand warmers (by the way, you need to buy these too). (Photos legend: Left - old formula, Right - new formula). The holes in the center of the headphone pads should be large enough for your ears to fit inside.
