The outsole is flexible but not too soft, and will last quite long. We love Stride Rite! So far the battery life seems good; Ive only had them a week or so, thus I cant comment on longevity of the product. It was flakey and not helpful Not to hot. This blue tooth speaker surprised me. I like it better than classic (relax fit) crocs Overall: 9/10 I get the package, I open it. Or you can get #1 quality if you do it right and pay a proper price.
