You did not mention what diabetes you have ( if any), for how long or what age you are. ( or what possible medication you are on.
I am T2 Both my feet can be fuzzy for long periods BUT I still pass the diabetic ” touch with a nylon whisker ” tests for feeling. The fuzziness varies with the time of the year , the weather , my mood ( and possibly blood sugar levels which are getting under better control ( HbA1c ca 7.5). If the numbness is sufficient to fail the touch test beware of any possible injury.
Standing, working in tight shoes, all can give you numb or painful feet. (Particulalry when you get older) Concentrate on getting comfortable footwear..
