I have a very hard time finding shoes which fit my feet properly. I have neither high arches or low, but if a shoe has too much arch, or the heel cup dips too much behind the arch, it puts pressure just forward of my heel, and my feet hurt. When my feet hurt, I am not a nice happy person. As such, buying shoes online is not practical for me. But I've found that Ecco's quality control is very good, so I thought I'd give it a shot. I was not disappointed. The odd thing for me is, this particular shoe in size 42 EU fits my normally US 9.5+ feet very well. I could not say that this would be the same for anyone else. Then again, as long as there is length enough for my big toe, I prefer to wear my dress shoes a little tight and break them in for perfect fit. This is especially true for ones I wear commuting to work and for going to trade shoes, where I'll be on my feet all day. These take just a little time to break in, but once they do, they are wonderful. Mine are so comfortable, I could probably walk further in them than any other shoe I own. The last pair were so comfortable, I wore them nearly every day for over a year and a half before the heel started to compress to the point where they started to hurt (as is the fate of all shoes I've ever owned). These also cost considerably less on Amazon than the local department store.
