My white and black Avanti Quattro fins match my BCD and Mares Reef wetsuit, so I always wear these together on tropical dives. The fins also give great propulsion in current but are not so heavy that they make your legs and ankles sore.

The Dive360 Take
The Quattro Plus is the direction we’d look for a versatile open-heel scuba fin with a straightforward setup. Its four-channel blade flexes through the kick to direct water backwards, while the bungee strap makes putting it on and taking it off easier.
An anatomical foot pocket and stabilising features complement the blade design. It’s a practical choice for recreational scuba divers who want a fin for regular dive days rather than choosing purely on colour — although coordinating your kit is still allowed.
Choose the size around the dive boots you actually wear. The guide below gives Mares’ size ranges, but boot thickness and shape matter too; a bigger boot doesn’t always belong in the same fin size as your everyday shoe.
