The feet should be observed daily, looking for any small abrasion, wound or redness.
The 4 places on the foot that should be taken care of if you have diabetes are:

Carry out daily exercise in the form of walks on level ground and at a good pace for at least one hour or you can also carry out an exercise routine at home according to your physical condition and your age.
Hygiene: cleanliness is also important, which is why we must wash our feet daily with lukewarm water (remember that the nerves that conduct thermal sensitivity may be damaged and we may not realize that the water is hot enough to cause a burn) and soap.
Drying: must be thorough, making an effort to remove moisture from the area between the fingers. In the event that you have excessive sweating, it is recommended to apply talcum powder after daily washing.
