ROB ALLEN SCORPIA Freediving Fins - Long Blade Plastic Spearfishing Fins for Underwater Hunting & Snorkeling

Definitely durable however since they are one piece you cannot upgrade them. If you have any intention of ever possibly getting better fins in the future, spend the extra 30-50 bucks and get seac, cressi, or mares or any other fin that has foot pockets that can be upgradeable. Now I need to go buy new foot pockets just to get better fins.In addition, pretty stiff and they float so not for surface swimming at all. Swimming out to deep depth and treading water is a pain is the a** because your feet float up. Also, swimming in tunnels and caves is dangerous because your feet float up and can get caught on the roof of the cave or tunnel, this has happened to me twice at a decent depth.I mostly dive 15-35 feet in Hawaii, training to go much deeper.They do look cool though.- Also, runs very large -Im a size 10.5 and have to wear 2mm booties with my size 8-9 finsThey were for my girlfriend. They came a little too large. And the plastic stays in the position it was last bent to, doesn’t move back to the original position at all!Now, for the price. You’ll get decent freediving/spearfishing fins, but if you take it seriously, there’s some other options out there that aren’t much more expensive and are fiver glass or just better plastic.Normally rob Allen stuff is great, a little disappointed with these fins.But please don’t let that discourage you, if you want decent freediving fins, and want to save money where you can. These are great.I’m comparing them more to fiberglass ones I have, when really there is no comparison.Conclusion: decent fins for the beginner.I purchased the Large (10-11) sized fins. I wear 10 and 10.5 sized shoes for the most part. Even with wearing 3mm neoprene socks, these fins were too large and I had significant heel slippage. I'll be returning for a Medium sized fin. Overall the fin seems perfect for spearfishing, however as many have said already - these run quite big.For Abalone Diving on the North Coast, I don't think you can do better than these Rob Allen Scorpias. Super durable, the blades don't come detached from the pockets over time like most removable blade fins, and they propel surprisingly well. I've tried all types of plastic fins(Hammerhead, Beuchat, Mako) and these are by far my favorite. Ohh and hit 60' on a dive with these fins and didn't feel under gunned at all!Bought these for my wife in the Xtra Small size. She has tiny feet! These were perfect. She still uses dive socks, but these fins fit better than any she has ever had. She raves about them. They move her through the water with minimum effort. She dove with them in St. Thomas, Tortolla, and the Bahamas, and had no problems fighting the currents or getting down to depths of 40 feet. Great fins for people with smaller feet.The quality is very good. The size is not like described. They are a size bigger. If your shoe size is 9. Get the small.These do run big. I wear a 15 wide in Nikes and originally ordered the 2XL. They were huge even with 3mm socks!Seller shipped the XL’s right out and they fit perfect. Super easy exchange!Great free diving fins, you get a lot of thrust out of these. Personally I wear a low cut pair of socks with it for comfort and to ensure a more snug fit
