Luis,
Sorry that it may not be working out to be the best shoe for you (and that I'm using you as a guinea pig since I was considering the same ones). Similarly I have a foot that is so flat people are amazed, where yours are as flat as the earth circa 1942 mine are practically concave. The only shoes that I'm comfortable wearing are completely flat like top siders and penny loafers. Very few sneakers have ever worked well and even custom ski boots and orthotics have never worked. When I've looked at specialty options I've always been told not to bother...
The funny thing is that the S-works shoes have not bothered me (using their red insole I believe, the flattest one), maybe they don't have a support molded into the base. I was planning to look into the Bonts but alas that may not work.
I've heard that the Sidi Wire's don't have any arch support and rely on any footbed you may put in. Perhaps that is an option for the next pair. I might try them as well and will report back if I do. Or maybe you can be a tester yet again
