<human>: Give me the gist of the text in a nutshell

So I'm trying to get back into training again after half a year of depression and stress, but my feet keep spasming up while I'm running.  (I still can't break 3 miles because of this issue.)  I've got very high arches that I've never had success finding adequate support for in a shoe, but I've used the green Superfeet insoles in the past with good results.  However, that was when I weighed about twenty pounds less than I do now and I'm having a hard time finding shoes that the insoles fit into while still providing my arches the support in the right spot.   I guess what I want to know is what the benefit is to buying the $200+ shoes for high arches over using some cheaper shoes with good insoles.
<bot>: Can Frankensteined running shoes from cheap, general-use running shoes and fancy insoles work just as well as the expensive shoes for people with high arches?
