They cost anything from less than £20 to more than £250. So how do you pick the right pair? And will paying more make you run faster?

With the ‘Couch to 5K’ app breezing past 5 million downloads, and marathon season well underway, two listeners ask Greg: What will they get for the extra money? A shoe more suited to their running style? More cushioning and fewer injuries? And will a top of the range pair with a carbon plate in the sole make them faster?

Greg Foot gets the answers from biomechanist, Dr Hannah Rice and sports technologist Professor Mike Caine. Plus, running writer, journalist and world record holder [for the fastest marathon in a full body animal costume (female)], Kate Carter.

In this episode, Michael reveals how the part of your workout that often feels easier - running downhill after a brutal run up to the peak, or lowering down weights rather than lifting them up - is one of the quickest ways to improve your strength and enhance your workout. It’s the flip side of a lot of movements you’ve already been focused on. To find out more, he speaks to Prof Tony Kay at the University of Northampton who delves into the bizarre benefits of Eccentric Exercise. He reveals why the muscle-lengthening phase of exercise is more effective than the muscle-contracting phase… and how lengthening your muscles is the key to stronger muscles, bones, a healthier heart, and could even help burn more calories than a seemingly tougher workout when you’re finished.

Irene Davis is the founding Director of the Spaulding National Running Center at the Harvard Medical School. In this episode, Irene describes how her research of biomechanics and clinical work with running injuries, as well as research by others, has shaped her views on maintaining body alignment and foot health. Irene discusses her argument for the role of modern footwear in running-related injuries and how minimalist footwear helps resolve the subsequent biomechanical issues.

We discuss:

• Irene’s path to her Ph.D., her entry into physical therapy, and her interest in biomechanics [3:20];
• How Irene’s thinking about the use of orthotics has changed [7:15];
• The evolution of the human foot and the transition from walking to running [10:30];
• The evolution of shoes and its impact on running injuries [17:30];
• An overview of running injuries [26:00];
• Cushioned running shoes, heel striking and impact forces [29:30];
• Shin splints [33:45];
• How heel strike patterns promotes knee stress through rate of loading [35:30];
• The critical importance of exercise [42:15];
• Impact forces and injury potential [45:45];
• How shoe cushioning alters impact forces despite forefoot striking [49:00];
• An overview of minimalist shoes [52:30];
• Irene’s protocol for transitioning people out of orthotics [58:45];
• Transitioning to minimalist shoes and a forefoot strike [1:05:30];
• Foot muscle volume, minimalist shoes, and orthotics [1:07:00];
• The recognition of the importance of foot strength in podiatry [1:09:45];
• Minimalist shoes across the lifespan—from children to adults [1:12:30];
• Why learning to forefoot strike on soft surfaces is not the best approach [1:20:00];
• Knee valgus and factors related to knee injury [1:21:45];
• IT band syndrome [1:28:30];
• Physics and ground reaction forces [1:33:15];
• Irene’s approach to retraining a runner’s gait [1:36:00];
• Case study—How the transition to minimalist shoes decreased injury and improved performance [1:42:15];
• Importance of proper movement patterns and the negative influence of our modern environment [1:45:30]; and
• More.
