You need a shoe with stability. They usually have a 'roll bar' on the interior. I wear Saucony Trigons. Go to a store that sells running shoes. Tell them you need a stability shoe. I also have orthotic inserts in the Saucony as well. A physical therapist casted my feet to make the orthotics.

Also, the EMG won't find small fiber neuropathy. For that you need an epidermal nerve fiber density biopsy (skin punch).
