Flat feet commonly exhibit something called "overpronation", which describes the over flattening of the foot's arch when standing or when the foot hits the ground when walking. Samurai Insoles addresses this issue with a different approach, says Dr. Lembo. "Many orthotics aim to control overpronation, but they usually restrict it WAY too much. Your foot needs normal pronation for shock absorption. So when it's restricted too much, it's really uncomfortable for your feet, as well as your knees and back. On top of that, people with really flexible flat feet like mine often can't tolerate that type of device."
What makes Samurai Insoles different is a piece of technology that isn't apparent at first, making them deceptively simple looking. "We use a unique orthotic shell, and we've tucked it away in a comfy padded envelope of material. It's really our secret weapon. Our orthotic shell decelerates overpronation, instead of blocking it. So, it flexes and springs back as you're walking. It's like having a spotter for a weight lifter, just enough comfortable support for your foot to get the job done."
