The smallest thruster in the Futures Legacy line, built in Honeycomb and priced at $125 USD. Futures rates it for surfers between 95 and 135 lbs, which makes it the grom and lighter-rider entry point to the neutral template.

Quick specs

Setup: Thruster
Template category: Neutral (all-around, versatile)
Construction: Honeycomb
Ride number: Balanced 5.3
Size: Small (95 to 135 lbs)
Wave type: All types, all conditions

Futures splits its fin line by template category before size. The Legacy Series sits in the Neutral bracket, meaning an even balance of drive and release rather than a rake or pivot bias. The F4 is the small size in that family.

Construction is Honeycomb, the same build Futures uses across most of the Legacy range. Futures gives the F4 a ride number of 5.3, which it labels balanced, sitting midway on its own scale between loose and locked in.

Weight range is the deciding spec. Futures publishes 95 to 135 lbs for the F4, so if you are heavier than that the F6 or the F8 is the correct set rather than this one.

Pros & cons

Neutral template works across most board types rather than one style
Honeycomb build is the mid-tier Futures construction, not the entry plastic
Sized specifically for 95 to 135 lb surfers, a band most fin lines skip
Also sold as a five-fin set if you want quad options on the same board

No published customer or editorial score on the sources checked
$125 is not cheap for a small-size thruster
Neutral templates trade outright drive for versatility
One construction only, so no carbon or Alpha option in this size

How it surfs

No retailer or publication we checked publishes a numeric score for the F4 Legacy, so the figure on this page is an estimate based on published specification and price against the fin sets we already track.

In practice the neutral template is the safe first upgrade off stock fins. It does not force a surfing style on you the way a heavily raked template does, which matters most for lighter and younger surfers still working out what they like.

If you are shopping for a lighter surfer and want more hold through turns, the AM3 rake template covers similar weights with a different feel. For the same template in a bigger body weight, step to the F6 Legacy.
