Plus, the front of the sandal is so thin it bends under my toes if I scuff them on the sidewalk. There are also numbered tick marks on the adjustable exposed metal to not keep you guessing whether each side is extended evenly so thats a plus. The ear cups is a little stiff for my liking, but it is comfortable in long periods of time. The wool is not itchy and is extremely soft. I really am able to sleep much better. I wanted these for myself but they didnt have them in my size. for a while. With any of the other 3, I can put my right earbud back into its case and continue to listen from only the left. I wear a size 9 in just about every shoe I own, and these were WAY too big for me, extending well beyond the toes, and forcing me to cinch the velcro so much that the straps hung over in (too) long loose ends. The strap between your toes I didn?t even feel it.
