Relatively comfortable for a flip flop but not super-squishy comfort as some of the other reviews stated: not like a Birkenstock or Alegria footbed, but some contour and arch support. The supplied pre-cut, double sided mounting tape piece are too small and the adhesion too weak to attach a tile to a hard surface, like a remote control. Very reasonably priced and well made. This is a 5 star product. Pero estos vienen chicos :( Sugiero que los compren una talla más grande. We got two of them, this and the Amazon special black and red edition, to use them paired up, as advertised. Noticed very consistent and highly rated reviews. I would highly recommend if you want a real quality bluetooth speaker, this is it, you find no other place ! I reckon this will last a long time and the quality is excellent for what I paid £42. It worked so well!
