In order to reduce diabetic foot lesions, diabetic patients must master some of the following basic knowledge of diabetic foot care. 1, choose the right shoes and socks: moccasin leather shoes, sports shoes are the most ideal shoes. Shoe type is appropriate to choose a square toe, to ensure that the shoe is slightly wider than the foot, breathable and has a certain role in resisting external forces. Do not wear high-heeled, pointed, hard leather and plastic shoes, but also frequently check and remove any foreign objects that may be present in the shoes. Socks should be made of cotton and wool, which are both sweat-absorbent and breathable. Don’t wear socks that are too big and don’t wear socks with elastic bands. Change them daily and don’t wear socks with patches or tears to prevent uneven pressure on the feet and affect blood circulation. 2, properly do foot washing and foot care: To maintain foot hygiene, it is recommended that diabetic patients wash their feet daily.
