Craig GwynneYour feet work hard every day supporting your body, absorbing impact and adapting to different surfaces. But they often get ignored until something goes wrong. Imagine your shoes alerting you to foot injuries before you feel any pain, or your socks warning you about the risk of an ulcer before symptoms even appear.This is the promise of newwearable foot technology.About one in five adults in middle and old age experiences foot pain, ranging from minor aches to problems that limit daily activities. Some foot conditions, particularly linked to diabetes, can be life-threatening. Patients with foot ulcers caused by diabetes have a 40% chance of dying within five years of symptoms appearing, which is higher than many cancers. If untreated, ulcers can lead to severe infections and even necessitate amputation.
