Doctors of Running: "PEBAX® material specifically seems to have the best energy return of the foams on the market."

Get an insole that gives, not takes... That initial step-in cushiony feel of a common insole can be misleading. While normal foams absorb energy (think of your memory foam mattress or comfort-centric insoles), PEBA foams combined with carbon plates store and release energy in meaningful ways, giving you back energy with each step. Compared to other materials typically used for insoles such as EVA or TPU, a special characteristic of PEBAX® polymer featured in the AURORRA By ARRIS insole is what is referred to as a "low energy loss." This means that when the insole material stretches with your movement, the foam efficiently stores that energy and then releases it when you step off, giving you an explosive feeling underfoot! Combined with a cutting-edge propulsion plate, this creates an incredible performance advantage already relied on by elite athletes winning world records, and now by you, because life itself is a marathon, too...

Scientific Report: "Stiff insoles appear to add an extra gear unavailable to the human foot, which can enhance muscular performance..."

Increased stiffness in the midsole and forefoot, according to research, leads to three key benefits. It reduces MTP joint dorsiflexion by limiting the flexion of the MTP joint, which decreases the workload on foot muscles during toe-off and conserves energy for forward propulsion. It enhances energy storage and return by utilizing high-modulus materials like carbon fiber plates that act like a spring to store and release energy, thereby improving running and walking efficiency. Additionally, it improves propulsion efficiency by creating a more rigid lever for push-off, enhancing force transfer to the ground, reducing muscular strain, and delaying fatigue... READ MORE >

Journal of Science & Medicine in Sport: "Increased midsole bending stiffness resulted in a redistribution of positive lower limb joint work from the knee to the MTP joint..."

Shoes featuring PEBA foams and carbon plates offer several key benefits for runners. They improve running economy by reducing energy expenditure and fatigue, leading to better walking mechanics and lowering injury risk over time. The increased midsole bending stiffness from carbon plates reduces MTP joint dorsiflexion and Achilles tendon strain, which can help prevent common injuries like tendinopathy and plantar fasciitis. Additionally, the superior cushioning capabilities of PEBA foams help reduce impact forces during running, decreasing the likelihood of injuries such as stress fractures... READ MORE >
