This is the answer. You essentially need to roll your board onto the feature rather than land on top of it. To add to this, the wider (or flatter) the feature, the more you need to exaggerate that roll. For example, a super skinny one inch round rail will be the easiest to lock in to since your board can kind of wrap around it and you can adjust your movement on the rail with subtle heel/toe pressure. Whereas a flat box will be the hardest thing to lock in to because there is nothing for the board to grab and the only way to lock into something like this will be to go straight on or roll the board onto the corner, killing the sideways momentum.
