Arris chosen by U.S. Army for study on continuous fiber insoles

Arris Composites (Berkeley, Calif., U.S.) announces its selection by the U.S. Army for a study on the use of advanced carbon fiber plates in military boots. 

Funded by the U.S. Army Natick Soldier Research, Development and Engineering Center (NATICK) and the U.S. Army Combat Capabilities Development Command (DEVCOM) through the University of Massachusetts at Lowell (UML) Heroes program, this collaborative research will be conducted alongside the School of Kinesiology and Nutrition at the University of Southern Mississippi (USM). Findings from the study are expected in 2025, with the potential to reshape future designs of military boots to improve soldier performance and reduce risk of musculoskeletal injuries.

Founded in 2017, Arris has produced a number of composite products in a wide range of industries, previously partnering with the U.S. Army and Devcom GVSC on lightweight vehicle seats. Most applicable to this military boot study, Arris developed a running plate for Brooks’ Hyperion Elite 4 running shoe, where Arris’ carbon fiber plate reduced weight, improved energy return and provided better recovery for runners. Building on its success in the “super shoe” market, Arris is now applying its technology to military footwear to develop carbon fiber insoles for use in military-issued boots. These insoles are designed and engineered to enhance daily movement, reduce fatigue and mitigate musculoskeletal injuries, especially in hot weather environments.

This ongoing study involves both bench-top and in-vivo testing to validate the benefits of carbon fiber insoles in military-issued boots. Prototypes of continuous fiber-reinforced plates have been integrated into hot weather combat boots and will be tested to assess their impact on running economy, lower extremity biomechanics and measures of functional performance.

“Footwear plays a significant role in the mechanics of movement, particularly for service members who operate in demanding environments,” says Scott Piland, Ph.D., professor and director at the School of Kinesiology and Nutrition at USM. “This research will offer significant insight into how we might boost performance and prevent injuries through the application of this technology. We are enthused to be part of this collaboration with Arris and UML.”

Project results are expected to influence both military and civilian applications, revealing possibilities for athletes and enthusiasts alike, as well as professionals and workers on their feet all day.
