Shimano WM Flash Boost

Shimano WM Flash Boost is a shallow-running jerkbait built to keep drawing eyes even when you stop it. Flash Boost suspends reflective foil on micro springs so the lure keeps shimming on the pause, while Scale Boost adds composite-pitch hologram realism that throws complex light through the water column.

Inside, Shimano WM Flash Boost uses Jet Boost weight transfer to help you reach fish that sit just outside normal casting range, then settles back into a balanced posture for crisp snaps and controlled suspends. Work it with short, sharp rips and measured pauses to stay in that 4–6ft zone around rock transitions, sparse grass edges, and wind-blown flats—ideal when bass or walleye track a bait but need one more trigger to commit.

What Sets It Apart

• Keeps fish engaged through the dead time, thanks to Flash Boost foil that continues to shimmer on the pause.
• Shows a more believable baitfish profile in clear or mixed light, thanks to Scale Boost composite-pitch hologram scale detail.
• Reaches key water efficiently and maintains a steady track after the cast, thanks to the Jet Boost weight-transfer system.
• Converts more follows into hooked fish, thanks to premium hardware with stainless split rings and sticky-sharp trebles.
• Covers shallow targets with clean start-stop cadence as a suspending jerkbait, and Shimano WM Flash Boost stays ready for the next snap.
