The bungee strap system is tailored specifically to each fin size, hence we have designated them as XS/S, R and XL. The length of the bungee is 18, 21 and 24cm, respectively, and in this configuration will fit the vast majority of divers. However, there may be instances when an extension may be welcome, such as when the user is at the upper limit of the foot size range for the given fin size and/or is using thick boots (dry suit or sneaker sole type wet boots). For this purpose we have included one extender per bungee, which increases the length of the strap by 1.5cm (hence splitting the difference to the next size). We strongly suggest first using the bungee strap system without the extender and verifying the fit in this configuration first. Only if the bungee seems excessively tight do we suggest to mount the extender. It is irrelevant whether this extender is mounted on the right or the left side.
With the new Mares bungee strap, donning and doffing a fin is a breeze, and the comfort during the dive is guaranteed by the new ergonomic heel cover.
Simple yet innovative … 100% compatible with the Mares fin line.
