From the treatment guide.
The exfoliation step here goes further than a Regular Pedicure, working through the kind of hardened skin that builds up on heels and the balls of the feet over months, not weeks. The massage runs longer too, since the goal isn't just clean nails, it's giving feet that have been carrying you around all day some real attention.
This pairs well with one of our longer massage treatments if you're planning a fuller spa visit. Booking both together also makes it easier for us to schedule enough time for each without rushing either one.
Worth the upgrade if you're on your feet a lot, whether from work, exercise, or just regular heel-wearing.
