Asics GT-2000 3 (£107, simplyfeet.co.uk)

The foundation of your marathon success, these lightweight trainers are built to keep your foot stable and cut the risk of chafing and blisters. The flexible, comfortable sole lets your forefoot move freely as you run, and soft landings come as standard thanks to the refract GEL cushioning, which your feet will thank you for.
