One shoe fits all, or does it?
More than ever-before running shoe brands are introducing new footwear to the market. Gone are the days when they just focused on 'stability' and 'cushioning' as the reason to create new designs. The ability for an athlete to have lighter, softer, firmer, flatter shoes, and so on, to enhance their experience of running is greater now more then before.
This also throws up the science behind efficient running styles and the fact that not all running shoes are suitable for all types of training.
Different shoes for different sessions.
When training for a marathon and the plan says' long easy pace 16 miles' that doesn't mean take your fast or carbon shoes out and blitz the pace. Like-wise, if you are driven to get that new pb at the next 5k road race, a pair of 300g+ training 'boots' will slow you down. Go fast and light.
The flex points and angles of shoes differ from model to model to offer a different experience and mechanical response. Faster running requires a greater heel lift and active leg recovery. Carbon plates and 'reactive' foams encourage a more efficient style, but not the most comfortable shoes in the store.
Don't just rely on one pair to take all the work. Vary and rotate your footwear options.
