Todavía estoy evaluando si los devuelvo, lamentablemente tiene menos pros que contras, principalmente ya tengo muy lástima la planta del pie, las traigo todo el día porque estoy en casa pero me lástima mucho porque son muy duras, es como estar parado en vidrios, el primer día lo soporte pero ya llevo 3 días y no puedo estar parado sobre ellas creo que ya me lastimaron por dentro del músculo. So I shut it down and the lady says "audio prompts disabled" after that I try to turn it back on and it gives me a half boot up tone, once, twice, then finally it just flat out makes no sound, cant connect to the phone.

The sole was definitely durable and appeared like it would hold up well in and outside. 2 RECEIVER.
