The Adidas_1s are the first trainers to contain a computer chip. Does this mean bionic running is finally with us? Sadly, that's still beyond these trainers, but they will make your evening jogs a whole lot more comfortable.

Using a sensor, a microprocessor and a motor, these ‘intelligent’ trainers ensure optimum cushioning throughout your run or workout. Unlike ‘stupid’ footwear, they adapt to your weight, your pace and the surface very quickly indeed.

This means that if you're running on hard concrete they'll provide some give, whereas muddy grass will see them harden up to give support. Now Wayne Rooney won’t be the only one keeping his brains in his feet.

They're not Stephen Fry intelligent, but the Ones do a grand job of adapting to different surfaces
