Hi Kelly, I have these and bought them as a result of the runners world shoe guide. I mildly overpronate (as I think most people do). I like them and have had no problems - have had them since August. We don't have specialist running shops where I am, but I did discover DW sports do gait analysis after I'd bought them, so I had it done and they agreed I mildly overpronate. They recommended done orthotic insoles which I have in the shoes.
All that said, I'm not a very experienced runner, so you may not want to take my advice! You are probably best to get a hair analysis done as that's what everyone has said to me. I don't know, mind you, if a gait analysis from a general sports shop is as good as one from a specialist running shop.
