free-running-trainers.jpgThere's been quite a buzz around 'free running' shoes for a little while now, so in this Olympic, athletic and all-round scarily sporty year, we thought we'd investigate the phenomenon a little more closely. Nike released a new range of free running trainers earlier this month, and this crazy spotted pair has recently popped up at ASOS, where you can buy them for £80.

So what's the difference between a free-running shoe and an ordinary trainer? The main visible difference is on the sole, which is designed to be particularly lightweight flexible offering barefoot-like freedom for the wearer. There's also special cooling technology on board, so the feet stay fresh, avoiding the sweaty side-effects we associate with more traditional trainer styles.

If you want to give Nike's free-running shoes a go, there are more styles available over at their site, but you'll find more crazy designs and interesting fashion forward editions at high street retailers like ASOS and Schuh.
