Remember in ‘Back To The Future 2’ (over 25's back me on this, under R 25's watch the DVD) when Marty Mcfly put on a pair of trainers that automatically changed to fit his size? Well Adidas have brought that technology one step closer to reality with its new trainer '1'. The '1' men's running trainer is billed as the most advanced trainer ever made. It features a small computer inside of the trainer that automatically adjusts the cushioning of the shoe so that the wearer has the best possible cushioning. At the time of writing '1' was scheduled for a midmay release date so you should be able to pick them up now. Make sure you got a bit of cash in your pocket, '1' are set to retail at around the £130 mark.
