Arlene, a below-knee amputee for almost 20 years, couldn’t believe the difference between her traditional socket and her new HiFi. With the HiFi, “it feels so much more natural. I don’t have to think about walking. That’s Amazing!” In my old socket, it “feels like I’m going to go down. The knee is going to buckle. It’s a little scary.” Arlene shows the HiFi can help users of all ages. Everyone can benefit from HiFi’s ability to provide added stability and control.
