Fins To Be Worn With Boots
Tecraclene ribs in the foot pocket afford an improved fit and permit more efficient transmission of the kicking action. The range of sizes is complete, from XS to XL size to better accommodate all requirements, including those of women and younger divers. The straps feature the ABS Plus (Adjustable Binding System) for single-handed adjustment. The Mares Avanti X3 is a successful marriage of comfort and power.
The Avanti X3 uses Mares patented design ABS Plus Buckles. It only takes one quick movement to easily open or close these buckles, even when wearing thick neoprene gloves. The double button release prevents the buckles from accidentally opening making them the most user friendly system on the market.
