... are, sadly, too comfortable. Now normally this sounds great, but I think that they are probably now losing their strength and rigidity.
So, on average, how many days skiing before a decent (i.e. not cheap as chips, but not 'race') boot needs replacing?
Is this highly manufacturer dependent? Is it highly skiing style dependent?
I don't really want to change my boots but if a replacement pair would improve control of my planks I guess I should.
The comments of our resident zoologists are eagerly awaited!

zammo,
On average, 30,00 flexes before the plastic fatigues. (loses elasticity)
Effects such as sunlight(uva/uvb) and extreme cold, have and effect on different types and colours of plastic.
Between +15 deg' and -15 degrees, an average poly-ester boot will stiffen to 5 times it's resistance.
Liners are designed to last on average 50 days. Some are better than others and should the boot be almost intollerably tight at the start, this should not cause a problem.
Different types of liners are available and will effect the fit and flex of the ski boot.
Ski boots flex(measured in Newtons) is measured with the original liners, changing the liner will change the flex, this can be positive as well as negative.
I'm no plastics expert nor engineer, these are statistic followed as standard my the manufacturers.

Well, the person's real but it's just a made up name, see?

Hmm. So I might be able to 'stiffen' up how they feel just by changing the liners, right?[/i]

zammo, I'm not sure, but I don't think that boots soften up much over time, indeed the shells on my old Langes were so strong that driving over them in a car didn't do much damage 
The liners do pack out with time, so if you feel your foot is moving about in the boot, or you have to clamp the clips down too tight to stop your feet moving, then it's time to replace them.
When I used to ski full time, I got about a season out of a pair of boots. Skiing part-time (plastic and 5-6 weeks a year), I kept my last pair for 10 years. The current pair are now 3 years old, I 'hope' to get another 3 years out of them, but now Lange have gone back to their original shell design, they might wear out quicker

Anyway, snowHeads is much more fun if you do.

Right then. New liners it is. Does each boot manufacturer have its own liners or are these generic? Indeed, if the latter, are there any particularly recommended brands?

zammo, We often switch/change liners between brand without too much trouble. There are also the option of; Thermo liners(Light,warm and help out volume issues), and of couse, Injection(Should be made hard/firm to generate good hold and to justify cost)
