These are my second pair, as the first one, bought second hand 6 years ago, have started to leak - I do a lot of walking in the bramble infested fields. Immediately after opening the package I knew they would be going back. but they do work. The two holes on the muffler side were rusted on my 4 yo 2017 RAV4. These are good ear buds. Arrived earlier than expected, sweet sneakers, five stars. Would have been nicer with a second layer. Light works as advertised. The arch support is perfect, the sole is slightly "cushy", and this pair doesnt hurt the space between my big toe and 2nd toe. It?s mainly for tennis shoes and flat sandals.
