Am I returning them, no. Braden Estan muy bien Comes in a nice package and overall extremely satisfied with my purchase. If they were lighter they would probably stay put. Im a UK 3/4 so my shoes are probably smaller than most but they all fit fine. Bottom line - not acceptable at the cost. I knew it was a cheap speaker so I was expecting something like this to happen. And did I mention it has a 30-months backed manufacturer warranty if you register your buds online (otherwise a standard 12-months). All that being said, it is very important to know when ordering these clogs that they do run smaller than Dansko and slightly narrower.
