I do t have pets or small children, and I don?t wear them outside. "NewItem". well, they won?t charge! The only thing you have to watch is the weights sway if you pull down to fast . This my third pair of Z Cloud Chacos and by far my favorite style. Neutral color plus soft leather but just ridiculously large. Ningún problema. My recommendation is this: if you have narrow feet, order a half size down. They are easy to use out of the box and they connect to my devices quickly and reliably. Me gusto mucho, ahora puedo hacer sentadillas con mucha facilidad y sin que me marque los hombros.
