Hi Lizzy. I do overpronate mildly, so I tend to go for support shoes from the performance range. So not all out racers, but lightweight enough for me. At the moment I'm running in the following:-
Saucony Fast Twitch Endurance-excellent lightweight responsive shoe, but go for half a size bigger than usual as they measure up just a little smaller than other trainers in the Saucony range.
Saucony Praxis-another lightweight shoe, not quite as responsive as the FT, but great for longer distances. I wore these to do Cardiff as they've got a slightly wider toebox allowing for when the feet get a bit swollen after lots of miles:o)
Asics DS Trainers-I'm getting my last wears out of these, but although lightweight I prefer the FT-they're my favourites at the moment! Although the DS Trainers are a good solid trainer that feel quite firm on the cushioning side.
Nike Skylons-not really for overpronaters, but a lovely shoe that I can wear for short distances.
My other past favourites are Saucony Swerve, which again I've worn for a marathon. The only difference with these to the other Saucony shoes above are they are lower at the back on the heel, but I like the close to ground feel.
Hope this helps!:o)
