need new trainers - marathon!

Hi

I currently wear Mizuno Alchemy 10 trainers.  I am training for the Paris Marathon in April and would like to get some new trainers to continue my training with. 

As mentioned i currently have mizunos which are fine, but i've had them for over a year and are a little on the heavy side.

I over-pronate quite a lot and have occasional back problems so i need a stable shoe but i want one thats a bit lighter in weight.

I have had asics kayanos and saucony in the past.  The asics i found wore down very quickly and wasnt a massive fan for the money that i paid.  The saucony's were really heavy.  I have also had some other asics for faster runs which i liked but wouldn't give me the support for a marathon.

I have quite wide feet too to add to the problem.

I'm 5ft 8 and around 10 st...i tend to run quite heavy too (if that makes a difference!)

Can anyone recommend a good trainer for over-pronators (not mild) thats quite lightweight and will last marathon training and marathon distance?

Thanks

I find the runningwarehouse.com web site very useful for comparing trainers.  You can't buy from them as they are a US only web site.

It only has Men's Mizuno Alchemy 12 shoes listed, and suggests Brooks Adrenaline GTS and Saucony Omni as alternatives.  But it may be worth a bit of searching around the web site for more info etc.

I think you may struggle to find a shoe that matches all your criteria, as the structured shoes for severe over pronators tend to be heavy due to the additional cushioning etc built into them.

Personally I tend to buy my shoes online as I have a fairly standard gait & foot-strike, but in your case I think you would be best served by visiting some specialist running shops and getting their advice.  This will also give you the opportunity to try out these recommendations on a treadmill before buying.
