The Lost Grom fin was designed by Lost shaper Matt Biolos as a balanced Thruster set for smaller surfers. The Honeycomb material combined with the V2 foil gives the fin a softer flex pattern, optimal for generating speed. The Lost Grom has a fuller tip compared to other grom templates, providing additional hold through turns.
A lightweight hexagonal core gives these fins the feel of glass-ons. Engineered with a medium flex pattern, these are stiffer than Blackstix but more flexible than Fiberglass.
A V2 Foil is a V. Foil and Flat Foil blend. It takes the best speed generating attributes of the V. (at the base) and transitions into a flat foil in the tip for a controlled release in critical turns. Try the V2 foil if you are transitioning from flat sided fins. The benefits of the V. foil base will be noticeable but the change for your muscle memory will not be too drastic.
