I love doing tons of research before purchasing any product. I discovered Ecco shoe sole disintegrate within a few months of wearing. I can't post links, so you need to google "Ecco disintegrate", you will find lots of pictures, vedio clips and articles about such problem. I have a tried on a few pairs on and they ARE comfy, but would you spend over 200$ for just a few wears, that's up to you! Too bad....
