I love the sound from these earbuds. Has the center arch support helps my foot hang onto the shoe as I walk. ) The metatomical insole seems to be working. La bolsa no se movió durante todo el viaje de 1,400 km que hicimos y soportó las maletas muy bien. I purchased this for a recent trip across the country. Absolutely amazing headset! No soap. I have always worn a size 9/39. The case itself is firm and thick. Looks sturdy on outside.
