En mi punto de vista el woofer le da un efecto extra o sobrado, ya que ayida a dar efecto de vibraciones en explosiones, bajos sonidos, etc. Not just a bit of rubbing. The only downside I can think of is when she first started walking right after a year I got her crocs and she hey did seem to be a bit clunky for that stage. So light and comfortable, I have very broad feet and these are perfect they don’t pinch anywhere, you forget you have sandals on they are so comfy 💖💖💖💖💖 no side support at all. Ive had them on for a few hours and they dont make my feet sweaty, although that might change once the heat is cranked up in the house. ) The material is strong and it shows no sign of ripping or unravelling. But with a tough rubber sole, will also stand up to excursions outside the house. Very upset with the soundstage. I have had the soundsport free for about 2 weeks.
