Mares Avanti Quattro Power Fins — 42

A full-foot fin built around four blade channels

The Mares Avanti Quattro Power combines a closed, anatomical foot pocket with a four-channel blade and rubber-reinforced side ribs. This listing selects Camouflage in size 42. It is the full-foot Power model, so the pocket and blade identity matter when comparing products carrying the Avanti Quattro name.

Match the closed pocket to your foot

A reinforced heel forms part of the full-foot pocket. The source describes wear against the foot or with a thin sock, rather than over a bulky dive boot. That means the selected pocket size is a central fit decision, not something an adjustable rear strap can correct.

Use the size 42 selection as the starting point and check Mares’ fit guidance for the exact model. Do not transfer an open-heel fin’s size label to this closed-pocket design without checking the fit.

Four channels and reinforced ribs

The blade uses Mares’ four-channel Channel Thrust design. The channels shape how the blade deforms, while rubber-reinforced side ribs support its edges.

Who should consider it

The retailer positions the Avanti Quattro Power for freediving and spearfishing. A full-foot pocket and the selected blade format are relevant if those activities and that style of fit match your use. They do not establish a universal advantage over every longer blade or open-heel design.

Before buying, verify the Power model, full-foot construction, Camouflage finish and size 42 together. The product image is a model/color illustration; it is not a way to measure the actual foot-pocket size.
