Running should be one of the most natural actions of the human body. But however simple it may seem to put one foot in front of the other, debate rages over the most efficient way to run. In fact, poor running technique could hamper your speed

Weight 164gEvaluation Nike says this is ‘great for all road-race distances up to the marathon for efficient runners’. At 164g, we’d probably change that to ‘up to 5K’ for all but elite runners. It actually has reasonably perky cushioning (though we
