Nike's lightweight Lunar1

Anyone who buys Nike's latest Air Max Lunar1 is going to spend the majority of their time looking at their feet for two reasons.

Firstly, because they're exceptionally good-looking: the no-sew upper mesh of the Photo Blue colourway is a gorgeous blend of urban grey, blues and blacks - and that's before you even notice the delicately speckled Air-Sole.

But the foremost reason for ankle-gazing isn't due to the aesthetics - it's to remind yourself you did actually put them on. The Lunarlon midsole and Air-Sole units give the shoe a super lightweight construction, making it 28 percent lighter than the decidedly slender Air Max models.

Available for £105 from Nike, you won't be able to blame "heavy shoes" for your slow 5K time any more.
