the best thing for your feet is GOOD blood glucose control As near as possible to NORMAL[about 5 nearly all the time. That way the feet stay healthy and you can treat them pretty much as non-diabetic.
If however, your feet are not healthy, get an appointment with the podiatry department. In England, you can refer yourself. Get any problems sorted and ask for their advice.

Ps I treat my, Healthy feet, as a non-diabetic would. They scored 10/10 on their last checks. I use cream and a rasp if necessary and since I am prone to ingrowing toenails as a result of the shape of my toes[not damaged by shoes} I clip the sides of the nails on my big toes to prevent ingrowers. I wouldn't recommend this to anyone else, but it works for my feet, which are definitely HEALTHY.
