According to fetch I have three pairs coming up to the 800 km mark. I bought one replacement pair of Salomon 3D Pro GTX recently in preparation and the cushioning feels less springy than the pair that's nearly worn out. The others are Asics 2110 and 2140. I'm trying to wear them out but they all keep on going, with no injury problems either.
The conclusion for me is not to throw them out automatically - think of the environment! It maybe helps I only weigh 58 kg and wear them evenly. YMMV.

I have a pair of Mizunos which I bought just for races. I must admit , that when I put on a new pair, they feel great and I'm sure that I gain 3 or 4 seconds per mile. I do agree about the cost of a physio. A "good" pair of shoes is about the same as two visits. Thanks for your advice everyone.
58kg? I'm a skinny stick but I'm 70kg, big bones - it must be. (180cm in height)

According to this site's BMI calculator I'm well inside the normal range with a BMI of 20
As regards racing shoes, there must be a benefit for the lighter weight, but I have never seen any kind of pendulum physics analysis of swinging a weighted foot maybe 1800 times per mile run, but it must get noticeable energetically, after a point.

I spoke too soon. I found this in a paper on shoe protection and running performance:
"It is commonly believed that wearing lighter shoes with fewer protective features cansave energy. While oxygen uptake my be reduced by 1% or so for every 100 grammes of shoeweight saved, the runner’s kinematic adaptations to reduced cushioning has been found toproduce a similar increase in oxygen consumption. Therefore, most runners have little to gain byselecting shoes that lack risk-reducing features."
So minimal cushioning is bad for you too: you don't really gain anything energetically overall, and the risk of injury is greater with minimal cushioning.
