3 LA SPORTIVA HELIOS SR £100
These have a lightweight and springy feel and the upper has great fit and flexibility to go well with that midsole flexibility, particularly at the forefoot. The cushioning is set for a speedy ride while the lugs and level of stickiness on offer from the rubber outsole give a confident feel on a mix of underfoot conditions, including soft ground.
Pushing the pace is easy enough in these shoes although for longer runs or tougher terrain you may feel you need a shoe that is more rugged. But for speed these are hard to fault..
