I changed from Asics 2060 to Nike Air Structure Triax and, after some initial blistering on the arches, have found them excellent. I also have had good experiences with Saucony, although I think their womens models are a fair bit narrower than the mens.
I am surprised your physio didn't advise breaking in your orthotics - when I got mine, my Chiropractor advised runs of 2 miles maximum for the first 2 weeks, building up gradually from there, to allow my feet & legs time to get used to their new position. This could explain your discomfort on your 14 miler! Also, did he know what shoes you were going to put them in - 1070s are stability shoes, and putting more stability in in the form of orthos may have overdone it. Check with him in case he assumed you ran in neutral shoes.
Good luck.
