The tights suppress the movement of the rear legs by approximately 11%, reducing movement loss and promoting forward propulsion. They also use fabric that reduces energy loss when lifting the front legs, supporting swing movements. (Approximately 10 points less energy loss compared to our previous product (energy loss at 100% stretch recovery)) Furthermore, they maximize the functionality of the tights by providing support with moderate compression around the waist and hem. They also feature a non-slip lining. (Researched by ASICS Institute of Sports Science)
