You do not need to use a pumice stone for dry skin on your feet, particularly if using it causes your skin to peel.
However, if you regularly use a pumice stone as part of your usual foot care routine, independent of mikveh, then you should also use it when preparing for mikveh.
Dry feet are not a
chatzitzah. Hard skin also is not a
chatzitzah, but it is customary to soak your feet in warm water during your
preparation (and/or use moisturizing cream on your feet for a few days prior to mikveh) to soften any hard skin before immersion.
