PLEASE NOTE: This comes with a set of four, not the two shown in the ad picture. First off I have been a Teva fan for years, I took a previous pair all over the country on hikes and all sorts of random campouts, it was time to get a new pair. Crocs are annoying in that you never know if you need to order up, down, or exact. This is the 3rd set of earbuds I had to buy my husband in the past 3 months. The internal ear cups are silk lined, well padded, and provide a very adequate cushion to the ears. A very tiny complaint I have is with buying shoes like Booties or Boots. But on a typical residential side street, no traffic, voice is super clear. The extreme ups and downs placed enormous physical pressure on the flip-flops, but again, they were an extension of my body that never complained, so I took for granted their perseverance without a single protest. The manufacturer has diagrams in the lid of the box that explains things in pictures, but text would be nice since the symbols were not obvious to me. There is a little draw string at the base of the toes to tighten the slipper.
