Be Careful!  Follow directions.
First use was easy- I have Super calloused feet.  Used before bed for recommended time.  Feet were soft but back to normal mid-day.  Second use I slept in the booties.  Soft feet but about the same amount of time until back to normal.  The exception:  24 hours after sleeping in them, I developed massive case of hives on both feet.  If you are prone to dermatitis, don’t use.
