Great fins for scuba!I bought these to replace a well used pair of Mares Quatro. I wish I would have done it sooner! Comfortable foot pocket. Great spring strap! Good propulsion.Good fit, work well,I don't normally write reviews. But these were so worthless on my diving trip that I feel compelled to save people some money.These fins provide little to no actual forward motion. And as such are completely worthless against even a minor current. I spent the majority of my trip borrowing fins from my dive shop (the owner and I swapped fins underwater and he was as shocked as I was to find just how little power these fins deliver) so I could dive.After our first dive, we reviewed the video and found that these fins have so little stiffness that they fold nearly in half on a normal kick. Now, this wouldn't necessarily be an issue, except that they don't unfold until the kick stroke is completed and your leg is returning to its rest position. Rather than propel me through the water, these fins were simply being drug through the water.Seriously, don't waste your money. Go buy something like Jet Fins or Mares.Great fins. Elastic strap is great.Great set of fins. Took them to Hawaii and had a great time. Great price too.Fit great,, only used in the pool so far, comfortable with our without sock. Fits much better with sock.When ordering this product be aware they are only selling 1 fin not a set. I ordered for a planned dive trip and received only one fin not a set of fins.Bad ass fins
