I've used heel loops a few times, and they are really good for keeping your feet there. They are great until you stack it, one foot comes out, the board twists around while your other foot is still in there, and you have a very very sore ankle.

Haven't used since that day, and you just learn to either tighten your footstraps, flex your toes to keep the board on your feet, or buy new footpads...
All the best in whatever you decide to do
