Hubboards Air Hubb Swim Fins and their long awaited Dubb Zero performance flippers are as big on comfort as they are on propulsion. Malaysian rubbers built to last and built to comfort any wear and tear you might feel around your feet. The Hubboards flippers are popular as for their tireless testing regime which saw the Air Hubb fins and Dubb Zero fins donned by both Jeff Hubbard and Dave Hubbard in an effort to create the ultimate swimming fin which gave an equal amount of performance in terms of both propulsion and comfort. The---- final results are as follows in the images below. Jeff Hubbard maintained his dolphin cut shaped fin opting for more power in the blade and better control in the face of the wave. Meanwhile Dave Hubbard opted for a blunt cut allowing him a more manoeuvrable option when facing waves in the Drop Knee stance. Whilst he cut down on surface area Dave was sure to include similar comfort features and strengtheners the same as his brother. Each performing at similar levels, the only question that remains is whether you prefer prone or drop knee. Don’t thanks us, thank the talented men behind Hubboards bringing to you the best in fins in the Dub Zero and Air Hub flippers.
