as usual - go to a decent running shop, get your gait analysed and try a few pairs based on that to find what feels most comfy.
sure - we can advise, but as we can't analyse, any advice we give is pretty worthless....
I'm 16stone with neutral feet and normal to high arches - I run in Asics Nimbus but that's no guarantee that they would be right for you
