I am not a pedicure person, so...months before the summer is when any foot preparation begins. Step 1: Cut my toenails on a straight edge. My hairdressing aunt told me this to help avoid ingrown toenails. Step 2: Keep my feet moisturized (this is kind of an all year thing). Step 3: Continue with step 1 and 2.
If I was into nail polish, then I'd apply that closer to the time I was going to go sockless.
