Move freely after canceling Speed Booster.
Speed Booster allows Samus to run more than 3X her normal running speed. She can cancel her run to store the energy, at which point you can do Shinespark. Which is a move that has Samus fly in any direction until something stops her. Before you do this, you can do everything as long as you don't neutral jump. Use this freedom to reposition yourself before releasing Shinespark.
