I have seen lick granulomas in that area a number of times that look quite similar (and used topical Synotic and Banamine to clear them up. Though there is usually another underlying issue that caused the lick granuloma to begin with, in the foot often an infection of the nail or even bone in the toe). However you said he hasn't been licking his foot. I assume you would have noticed if he was obsessively fussing at his foot prior to this appearing.
I also recommend a biopsy, it's hard to say exactly what it is. Things like this can often come back inconclusive, and be sort of trial and error to get rid of. Good luck.
