The source’s weight figure is tied to a particular size and is not clearly a universal figure for every pair. Ask the seller to distinguish single-fin and pair weights. Keeping that question separate prevents an apparently lighter option from being compared on the wrong basis.
Compare an open-heel fin as part of a complete foot-and-boot combination. The pocket needs room for your actual footwear, while the heel system should hold the foot comfortably without forcing a larger pocket to feel secure. A useful fitting session includes putting the fin on and removing it with wet hands or the gloves you normally wear.
Blade shape, stiffness and overall weight can change how a fin feels, but a product photograph cannot tell you whether it suits your kick. If possible, try a similar style in a supervised session. Consider packing length and replacement straps alongside the underwater fit.
It is part of the model positioning, not a verified weight for every size. Ask for the actual selected pair’s weight and whether any quoted figure refers to one fin or two. Compare that figure with your packing needs while keeping pocket fit and handling as the first checks.
Use the model’s size chart as a starting point, then check it with the footwear you intend to wear. Boot sole thickness and the height of the instep both affect the fit. An open heel gives adjustment at the strap, but it does not make every foot pocket interchangeable.
No single blade suits every diver or kick. Consider your comfort, the equipment you wear and the techniques you have learned. Ask an instructor about trying the style in the water before changing your whole setup. Marketing descriptions of thrust are not a substitute for a useful personal comparison.
