We both have similar feet! I've a flat arch and warm up by stretching my toes towards me leaning into a lamp post for 10 reps. This stretches the mid foot and is a good preventative measure for plantar fasciitis (the pain in the midfoot felt by low arched runners!).
The best trainers I've had recently that offer a good arch support are Saucony fast twitch 6.
They are light and very fast; but bear in mind that you might get a bit of skin rubbing in the mid foot due to the arch support for a few days. They are optimised for a good mid-front foot strike so they'll probably do wonders for your running form over time.
A great trainer on a budget that is v comfortable for longer runs is Adidas Duramo. I take those on 16+ mile runs.
I was wondering if you had any tips for people with flat arched feet. I didn't have the proper shoes for it before and my feet ached horribly but I'll hopefully resolve that issue soon with a new purchase. but from all your running experience i was wondering if you'd experienced this yourself or had running team-mates with similar issues and could drop some knowledge! i really want to run but it's just not fun when my feet start killing after a mile and a half.
I'm trying my best, but I quite often struggle to express my thoughts. Sometimes I don't have the knowledge to reply. That's the problem because I like this section more than NSB (hell house) but I'm apprehensive about my boxing knowledge.
Should I stay in the history section, or NSB which is more "newb" freindly but infested with parasites?
