First off, they are a step in design, with nothing over the toes, and a built in heel strap. They're held on with two straps over the top of the foot and have a keeper leash to go around your ankle/calf. The keeper leash has a quick release buckle, the over the top straps do not. One of the online reviews I read before receiving these opined that quick release buckles for the two straps would be an improvement. I disagree. The tightening straps are easy to release (just lift the tab and they loosen up immediately) and quick release buckles would make putting the fins on harder (in my opinion).
Fit and finish was fine, they're a heavy rubber/plastic like most fins. More rubbery than the cheap ones, more plastic-y than the high dollar ones. All straps and buckles are pretty standard webbing and plastic, easily replaceable at need.
I definitely like the addition of the keeper leash as the fins feel neutrally or negatively buoyant.
As for the actual kicking, definitely less effort on the calves, but a bit more on the thighs. Overall a good experience, and walking in them, even in soft sand was way easier. In dive fins walking forward in soft sand is pretty much impossible, with these fins, you're not in a hurry for sure, but it's doable in a duck waddling, awkward way.
The hard(ish) nature of the material, and the design themselves require a dive boot or wader boot or water shoe. I tried them with just a fin sock around the house and it's painful. Since we use stocking foot waders, we just put our dive boots on over them without zipping them up, super comfy.
My son was able to get foam on the front of his tube at full speed (water polo, swim team and 30 years less mileage on the chassis than old dad) and I was able to make respectable speed.
I'm happy and consider it money well spent, but they weren't the come to jebus moment that a lot of anglers and divers seem to feel when trying this fin design. Not knocking it, but I won't be effortlessly pulling any skiers behind my tube is all lol. Tight lines gang.
