Not sure how waterproof they are, but I?m using them for just outside to smoke. These actually hold up after exercising and will not fall out. honeeeeeeyyyyyy, it was bomb. I was concerned after reading others remarks about their stiffness and discomfort but amazingly I found them totally comfortable. 5-6 . Weve tried for over a year to get rid of them. Bought these for my daughter they are amazing great sound great fit she absolutely loves them I definitely would recommend ?????? Just save your money for the second version. 99 in normal circumstances. Love this shoe but runs very small.
