Mares Avanti Quattro+ Fins is described in our source listing as open-heel fins with a bungee heel strap and a channelled blade. They are worth considering if you already prefer a boot-and-fin setup. Check the foot pocket with your own boots and compare how the bungee feels during fitting.

The Quattro+ name identifies this particular open-heel version, rather than every fin in the Avanti family. Look at the selected size and strap arrangement together. A familiar model name is useful for narrowing a search, but cannot decide the fit of your boot.
Compare an open-heel fin as part of a complete foot-and-boot combination. The pocket needs room for your actual footwear, while the heel system should hold the foot comfortably without forcing a larger pocket to feel secure. A useful fitting session includes putting the fin on and removing it with wet hands or the gloves you normally wear.
Blade shape, stiffness and overall weight can change how a fin feels, but a product photograph cannot tell you whether it suits your kick. If possible, try a similar style in a supervised session. Consider packing length and replacement straps alongside the underwater fit.
Yes. Check the pocket and heel strap together with the boots you plan to wear. The bungee needs to hold the heel comfortably without compensating for an unsuitable pocket. Ask about the supplied strap and approved replacements for the selected size rather than assuming every Quattro+ option is identical.
Use the model’s size chart as a starting point, then check it with the footwear you intend to wear. Boot sole thickness and the height of the instep both affect the fit. An open heel gives adjustment at the strap, but it does not make every foot pocket interchangeable.
No single blade suits every diver or kick. Consider your comfort, the equipment you wear and the techniques you have learned. Ask an instructor about trying the style in the water before changing your whole setup. Marketing descriptions of thrust are not a substitute for a useful personal comparison.
