Fiberglass fins with inside foil
Base: 4 1/4" 110mm
Depth: 4 1/2" 115mm

The inside foil and reconfigured angle means your board generates speed easier and has better acceleration out of turns. It will make smoother rail to rail transitions while allowing you to commit more of your weight to each turn and draw tighter more powerful arcs. The fiberglass and foam construction is super light! It's engineered with a progressive fiberglass flex pattern to give you more snap out of turns.
