Momentarily drops the L-Button when being held down. Thinking I need a second pair. The arch support is in the right place so it provides excellent support. Reefs are the best, I wear mine everyday at the least to run to the car or take out the trash, they stay resting by the back door. It?s a little tough to push the vehicle across concrete. The shoes are great quality. Pustekuchen. I cant really wear the in the ear canal earbuds. These are exactly as expected. I leave it charging at night and use it here and there throughout the day and havent experienced battery issues or running out of power.
