Product Information


The Avanti Tre diving fins are equipped with a closed, orthopedic foot pocket. They are specifically designed and constructed using materials that make them well-suited for recreational diving and snorkeling in warm waters. The foot pocket is made of thermoplastic rubber, which provides a comfortable and orthopedic fit. This allows for barefoot use or wearing with neoprene socks. The instep and heel areas of the foot pocket feature a border with varying thicknesses, ensuring durability.

The Avanti Tre features the Channel Thrust technology, which allows the fins to maximize the flow of water, therefore moving a greater amount of water, compared to other fins of the same size. The result is greater thrusting power with the same amount of effort.

The main features of the Avanti Tre fins are:

• Foot pocket designed with orthopedic considerations
• Three channels for optimal thrust
• Medium-sized blade, great for traveling
• Made with long-lasting durable materials
• Stabilizing trim tabs

For care and maintenance, carefully read the instructions that come in the packaging to properly maintain the product.
