Trainer designed to reduce runner injury
29/01/2020
The shoe is said to be stronger and more durable than previous versions, with three distinct layers to keep the foot secure. Higher foam stack heights give a softer feel, and a wider shape is intended to give a more stable running experience.
Nike said the shoe reduced injuries by 52% in a study of 226 men and women during a 12-week run training programme. Defining an injury as missing three or more consecutive runs due to running-related pain, the study found that 30.3% of Air Zoom Structure 22 runners experienced an injury as compared to 14.5% of React Infinity Run runners.
