The Price Is Right
If you're forking out the best part of £100 on a pair of shoes, it's only right that you know what it's going on.
At the top end of the price scale, you're looking at trainers with the latest designs and technology from the brand in question. This could be functional, like a super-light sole or new breathable upper material, or purely aesthetic, for example the new season's colour way.
These shoes will have been top of the range in the last year or so, now overtaken by the latest releases. They may still feature some of their brand's big technology (such as adidas's Boost sole material), but in an older design. Unless the brand has released some pioneering new kit (which your salesperson will be quick to tell you about), these shoe designs may not be vastly different to their more expensive siblings.
This is where the difference really starts to show – these shoes are more likely to be made from industry standard materials, which are heavier and not running-specific like bespoke technology developed by sports brands. That's not to say that you can't run well in them, but if you're looking for a real performance boost it's worth splashing out a little more.
