Sadie and Ginny both get corn chip feet, but its not a smell thats ever bothered me much and we really don't smell it unless a stray paw makes its way close to our faces.
Baby wipes are a great invention for all things sheltie related. I use them for all kinds of sheltie related things, feet, face, ears, pants, etc. They're great for getting rid of bad smells and oily substances.
