PFC Stockings
The stocking therapy group will be given PFC shear reducing stockings to wear. PFC Stockings: A pressure and friction reducing stocking. The novelty of the PFC Sock stems from its innovative double layer structure and technological fibre composition. These simultaneously and significantly reduce both pressure and friction in a format that is practical for everyday wear with therapeutic shoes in high-risk cases.
Standard Therapy
Standard therapy consisting of education, regular foot care and protective shoes and insoles. The standard therapy group will use the stockings they normally wear.
