Saucony Grid Trigon Responsive

[Deleted User]

I am researching shoes on t'interweb and am REALLY confused.

I have been told I have high arches and rigid/ equine feet but that my arches collapse horribly. High arches generally indicate underpronators, crashing arches indicate overpronators so I am a bit of both.

No idea what to do.

I remember when I ran a lot I had Saucony and i think they were Saucony Grid Trigon Responsive but not 100% sure. They were best shoes I have had. Don't think I had my orthotics in them though. These Nike Vomeros are not doing me any good, even with the orthotics in. they are ripped to shreds at the back of the heel - why would that be?
