I have REALLY REALLY bad hard skin on the bottom of my feet. I live in sandals almost all year round and it has caused me to have rhino feet 
I have been looking at those battery run hard skin removers, but I don't know which is best. Any recommendations? I don't want to use that stuff that peels the skin off that is so popular on here, I only have my sandals to wear and don't want to scare people!! It also has to be a product I can use at home because I am severely agoraphobic so can't see a, err, foot person (sorry, mind blank on what they are called!!)
Also, is there any particular products that are good for keeping feet in a relatively nice condition after they have been de-rhinoed?
TIA
