Sizing For The Orca DOL-Fin

To determine the binding strap size you need, take a measurement around your foot, while wearing the dive-boot or dive-sock you are intending to use with the DOL-Fin.  The DOL-Fin is not intended to be used with bare feet.  Take the measurement as shown in the diagram below.  

We recommend the Pinnacle Stealth dive sock for use with the Orca.  If the water is too cold for a 2mm sock, we recommend a soft sole dive-boot over those with a hard sole.  We discourage the use of dive-boots that have layers built up around the ankle that restrict foot motion as this configuration would promote fin orientations exhibiting more form drag. 

Use the following tables to select the appropriate Binding Strap size for you.

Orca Quick-Adjust Binding Straps

Size inches centimeters
Medium 11.4 to 12.6 29 to 32
Small 10.2 to 11.4 26 to 29

Note: Quick-Adjust Binding Straps may be adjusted approximately 0.5 inches (1.3 cm) smaller than indicated in this table by using the alternate slot in the belt slide.
