Avanti Pure

Product No: 410027


The Avanti Pure diving fins feature an open foot pocket, bi-material construction, and a comfortable design. The adjustable straps include an ergonomic heel reinforcement that reduces pressure on the Achilles tendon, making the fins suitable for use with bare feet or a light boot.

Product Information


Featuring a bi-material construction, the Avanti Pure fins combine durability and flexibility. Whether you choose to wear them with light boots or barefoot, the soft and comfortable foot pocket ensures a snug fit and maximizes comfort during your dives. One notable feature of the Avanti Pure fins is the ergonomic heel cover, which is designed to minimize pressure on the Achilles heel. This innovative design element, pending patent, adds an extra layer of comfort and reduces discomfort during extended use.

The Avanti Pure fins also come equipped with special elastic straps that provide maximum comfort during use, as well as when putting on or taking off the fins.
To prevent the foot pocket from rotating during use, the Avanti Pure fins include elastic strap guides. These guides ensure that the strap remains in the optimal position, enhancing stability and improving overall performance underwater.

The main features of the Avanti Pure fins are:

• Can be used barefoot or with light socks
• Bi-material open heel fin
• Soft and comfortable foot pocket
• Ergonomic heel pad reduces pressure on the Achilles tendon
• Elastic strap guides so that the strap is always in the right position
