Footbraking is not to be relyed upon at higher speeds, but it should be in your toolbag for slowing down at slow speeds.
-If you have the correct stance for a downhill longboard, you should pretty much be almost set to get ready to foot break. For a quick recap, weight forward, facing down the hill with hips and shoulders facing down the hill, and feet more paralel than perpendicular with the deck.
-With your front foot the same, or slightly more straight forward. Take your backfoot weight from ~15% on the board to zero.
-Move your back foot to the ground to provide resistance slowly while keeping the majority of your weight still on your front foot.
-Congrats, you are slowing down.
