Mares Volo Race Full-Foot Fins is described in our source listing as full-foot fins with Mares’ OPB and channelled-blade design. Start with the slip-on pocket and your intended use before comparing the blade terminology. Confirm the selected size and packed length, and try a similar style if its feel differs from your current fins.

The source names OPB and Channel Thrust as design features, not a test carried out for this guide. Compare how the fin sits at your heel and instep. A flexible-looking blade or technical label cannot predict whether the pocket will remain comfortable throughout a session.
A full-foot pocket needs careful sizing because there is no heel strap to take up extra space. Think about the way the pocket holds the toes, instep and heel, rather than relying only on a familiar shoe size. If you intend to wear thin socks, include them when checking the fit and the manufacturer’s sizing advice.
Also think about the route into the water. A fin that works for a boat session is only one part of a shore-diving setup. Compare blade length with your bag, and discuss the intended use with your instructor if moving between snorkelling, scuba and freediving.
Both source listings describe full-foot fins, but their blade designs and pockets should be assessed individually. Try the exact sizes rather than assuming one Mares size transfers perfectly to the other. Ask about dimensions and intended use, and let comfort and a suitable practical comparison guide the choice.
Do not assume a pocket designed for a bare foot will accommodate a dive boot. Follow the model’s fitting information and try your intended socks or footwear before deciding. For a setup built around boots, compare suitable open-heel alternatives as well, rather than buying an oversized full-foot pocket.
Confirm both fins fit comfortably and inspect the pockets and blades for damage. Measure the actual pair against your luggage rather than treating a product photograph as a size guide. Allow room for the rest of your equipment so that the blades are not forced into a sharp bend.
