The other small issue is when I flex my jaw, you get this odd creaking sound from the hard plastics in the earpieces (my wife asked me if I was grinding my teeth, so she could even hear it sitting next to me). I always wear size 5 shoes however in crocs and for work my feet swell. You know the pillows I?m talking about ? the ones that have been used and washed so many times that even when you?ve made your bed, it still looks awful (yeah, those type of pillows)? LOL. I?d recommend you go a little higher. Please remember to give your washing machine a wash with detergent after, with nothing in it, other wise you end up washing your relatives pjs, and other garments, which they really dont appreciate waterproofing, lol! I like the fact that it is compact. These are perfect for those who would be backpacking. I COULDNT HAVE CHOSEN A BETTER ONE. theyll work. They are steel tipped so boots offer an extra layer of protection when working outside which was purpose of the purchase.
