You may have noticed that using a stim while sprinting will slow you to a walk for 3-4 steps.
This forced walking can be ended early by opening your Map at the right time, resulting in the forced walking only lasting for a single step before resuming a sprint.
Alternatively, you can Dive at the same timing as you would open your map for the same effect.
There are a few different methods for timing your stim cancels.
These cues can be taken from the stim animation, sound effect, or by feel (the actual time between inputs).
