I realized the sole was super stiff and not broke in. Si me pusiera calcetas gruesas como se usa en invierno me quedarían apretadas y con el talón un poco salido. No care instructions included. Hope this wasnt too long winded for someone to skip over what could potentially be harmful. An incredible value at $79. Das Geld habe ich somit zum Fenster hinaus geschmissen. This headset has fine sound quality and works well with my company issued HP Elitebook. I have minor mobility problems so I need to excercise more. I reluctantly bought these and am dreadfully sad for waiting so long. Heavy duty.
