They have a hard sole so it’s more durable on hard wood floors which I like better then the last pair I got . and highly recommend to all my friends! The charging pad is a little bit tricky as my phone case is on the thick side and I really need to place it right in the center - probably more of my fault than products. Update: After three wears of about five minutes each, the elastic on the back of the left slipper stretched out, making them unwearable, as they wouldnt stay on my toddlers feet. Havent washed them yet. First week they hurt the top of my feet where it went but it is slowly going away during each use. By hearing protection, I’m talking about when the stage volume (guitars, bass, or whatever) is so loud it’s not healthy to your hearing to the point where ear protection of 20db is recommended. I ordered 2 dresses the blue and black in Xl size. Vale la pena por el precio. So I will just need to see how to properly wash them so they remain the same.
