I?m confused. I DO NOT Recommend at all. This is the first time I have ordered the Columbia Rostra PGF and It is awesome. When I turn my music up and ambient noise down I can?t hear a thing. Bought new Reef Fannings 3 weeks later (over twice the price but worth it). Estan super padres These dyed the bottoms of my feet black and no matter now much I wear them they still do it. I mostly needed these for watering my outdoor plants and thongs just slip and slide. I cant even hear my cat meowing on my own lap with these on. Love that these have a thick sole.
