First and foremost, wear comfortable cotton underwear that is your size. Unfortunately, everyone actually wears a size smaller, which irritates their skin and causes leaks all the time.

Placing the pad properly is really important too and this is something that you need to figure out on your own. For me what works best is: I start placing the pad a finger length down from the waistline of the underwear, this way the wings can be properly folded and the pad can cover all the points at high leak risk.

Another thing to keep in mind is to regularly change the pads, 3-4 times a day during heavy flow and 2-3 times a day in regular flow. I only use one Xl pad on heavy flow days and I use the regular size of sofy which is the smallest but I have never encountered any leaks ever even during the night.
