High-tech socks that monitor how people walk could cut the risk of foot and toe amputations due to diabetes.
The electronic sock contains a sensor that detects whether patients are putting too much pressure on parts of the foot that are at risk of ulcers forming, researchers say.
These ulcers — a complication of diabetes — can turn into infected wounds that become gangrenous. Chronic wounds are one reason why around 40 people undergo partial or total foot amputations a week in England.
