I'd say no at this point of time. The damage or wear has already happened in the toe area so unless you are going to have the brass nails removed and sunken toe taps put in I dont think its going to help. The heel already has a rubber tap.
Please go easy, if you want to bring up a good lustre/shine. Too much vigorous brushing may move the wax more than required and cause some blemish. I find finishing with a damp old cotton T shirt cut away is enuff.
