I would recommend this product. I was prepared for a significant worsening of quality and the minimal step off is more than acceptable. There is a thin fleece-ish/felt/?? liner/backing inside the upper that helps make them comfortable, especially from sweat. Al principio están un poco rígidas, pero con el uso se aflojan y quedan muy cómodas. horrible just despicable, these sandals are horribly uncomfortable idk what ever one else is talking about comfy ya right this is like having cardboard wrapped around your feet spend the extra ten bucks get some addias or nikes. It?s been much mor reliable in sound quality and holding charge compared to the much pricey headset from work. So far only pro"s no cons for me. Its unbearably loud at even half volume, a comfortable solo experience is found at 15-20%. It is actually maddening and lying flat is the only way (at least for me) you can do them up quickly. I have not used them but he says they are excellent.
