I've got quite flat feet, and have had my gait analysis done a few times, and always very obviously over-pronate. When I first started out running, I had a pair of very cheap neutrals, but on the basis of my first analysis switched to some Asics GT-1000 for some stability. The result was bad blisters on my arches and severe pain on the inside of my knee. The shop kindly switched me on to the neutral Cumulus, which I was very happy with. Last time round I ended up getting some Saucony Valor's as they were going cheap, and have got on OK with them (although I found them rather heavy). Saucony describe them as "light stability". But generally I've felt I should err in future towards neutral after my experience with the GT-1000s, and so I've just bought some Brooks Launch.
Anyway, I've never really looked very hard at the wear on my shoes, so it crossed my mind to do so the other day and noticed that the worst wear on my Valors is definitely on the *outside*, both at the heel and forefoot.
So, I guess the question I have is what weird kind of running do I do, seeing as I somehow overpronate (I'm confident that I do!) and yet wear most at the outside?! Also does this strange combination somehow explain the pain I had with stability shoes.
