Questions & Answers

Trish B : Can I wear these barefoot?darrick c : Hello Trish, no, those fins with the spring straps are designed to be worn with a boots. These fins are not designed for a bare foot.REBECCA D : If your feet are large enough, I suppose you could but it would be pretty uncomfortable. For size reference, I wear an 8.5 ladies tennis shoe and I have the XS fins. I wear a 2mm boot with mine and they are comfortable that way.
Karen B : I love my Oceanic Accels but looking for something better suited to strong currents. Are these much more powerful than the Accels? How do they cope with current?JOE S : These fins have great power and excellent for all applications of diving. They have a hinged middle that will collapse on your return stroke, easing the stress on your legs and allow for a more powerful thrust on the down/power stroke. They also channel water much more fluidly with the curved edges, giving you a more stable kick when extra power is exerted. The middle baffle also assists in channeling the water when kicking to provide maximum thrust on the power stroke.
Shopper : What is the weight of the manta fin?REBECCA D : I have the XS fins and each fin weighs just over 1.8 lbs, so both fins are just over 3.6 lbs. Obviously larger fins will weigh more.JOE S : right about 4lbs depending on size.
CHARLES F : How do these fins handle kicks other than flutter?JOE S : These fins work well with a frog kick and helicopter turns. Back kicking is a challenge anyway, but they can do the job if positioned correctly.SCOTT S : They work well but I find wearing a thicker. Boot helps with the fit otherwise they tend to twist in your feet when kicking really hard in sift current.joe m : For me, these are a stiff fin for flutter kicks. But for frog kicks, very good. Good power for frog. For flutter, too much effort for me. Everyone is different.
Dave S : I often do 2 dive trips per day which is 4 dives. I wear split fins to minimize fatigue. Will I have an issue with these fins? Are you worn out after a couple dives? Any keg fatigue ir cramping?JOE S : The Manta Ray fin is designed to maximize every part of your kick cycle. They have an assist at the end of your power stroke and the blade of the fin collapses on the return/up stroke to let it cut through the water with as little effort. They won't feel like split fins and you'll have to reacclimatize to the new feel of the manta ray, but you should get more power and not have much fatigue.ONEAL T : I doubt it. They are a medium stiff fin and extremely smooth. I have not had any issues.TIMOTHY F : I traded my split fins for these. I’ve had 5 back surgeries and that has affected my leg mobility. These fins worked much better for me. They are designed with a more natural angle for a parallel kick. The soft rubber in the center of the fin works as a propellant on the up and down stroke. I’ve only got good things to say about them. They work much better than the split fins for fatigue because you get much more thrust without losing water flow like through the split fins.MATT B : I just got these and love them. We were in Cozumel over Christmas and dove every day with no fatigue. My old fins had more flex kinda like a split fin and I found that those were more work than these.

M Series of Fins

Powerful enough and extremely responsive. I switch out to Triton Pros in heavy currents but an amazing fin in most conditions.

Brilliant Design!

Love them. Not as stiff as some people say. An all around brilliant fin. So pretty I’m afraid to use them sometimes. I have not tried them in extremely strong currents but I’m sure they would perform well. Similar feel to the SP Nova In my opinion. I like these more.

Excellent fin

These are excellent. I just did 15 dives with these and they are very comfortable, super quick to take off and board the boat in rough current, and do a good job at propelling me during dives.

Good fins

Fins work great, dove in some interesting currents and the performed well. Best feature is the easy on easy off straps. All in all very satisfied with the fins.

Speed, Comfort and Size - Top Notch Gear!

Super powerful! I was diving with split fins for years because of nerve damage in my back and legs. I bought these because I purchased a travel BCD/JetPack unit and they were shorter and fit on the side of the JetPack system perfectly. I figured I’d lose some speed and I’d be more tired. It was just the opposite. I’ve got a pair of splitfins for sale now. I’m sticking with the comfort and speed of these fins until I’m too old to dive.

The whole package. Performance and looks in one.

These fins performed flawlessly and were providing ore than enough propulsion for me (a novice diver) so I don’t regret putting my money on this set of fins. The stainless spring straps work great and are so much easier to don and diff than the standard rubber strapped fins.

Lightweight, lots of power

Tried this fin in my local waters suited up in my 5mm wetsuit. The fin performed great - lots enough power and great maneuverability. Bonus is they are pretty lightweight so great for travel and love the spring strap with my 5mm boots.

Preliminary review after opening box. . . dimensions and quality

Thought I'd post some things I haven't been able to find on the net. . Overall length: (to back of foot pad) Spring strap sticks out another 3.25 inches, but it's flexible. Foot pocket is 4" wide and 3.25" tall. Solid, but flexible. Will "squish" to about 5" wide and 2" or so tall. Handles about 3/4 of my foot. Blade is 9" wide for nearly the whole length of 14 inches. I wear a men's size 9 US and with 6.5mm soft boots they fit like a glove and are more comfortable than any full foot fin I've worn. Barefoot won't work. . . but a 3mm soft should be OK. Spring strap has 3 settings on each side at about 1/2 inch each position. The rubber pull strap slides on the spring, so you could adjust one side only and the loop will still center. Nice touch. My fitting with the 6.5 mm boot has the spring strap on the tightest setting so plenty of room for a larger boot. Had the spring strap pulled up over my Achilles and was still comfortable. Spring is not too stiff. Easy to pull on. I got the black and yellow, and the yellow kind of turns green towards the foot pad - I think they're gorgeous. Build quality and materials are excellent. This is not a "flimsy fin". the center channel is made of heavier material than I expected. It appears in will slightly flex for tooling around, but will probably flex more and really push the water when you turn on the coals. Hope it performs in the water as good as it is built, feels, and looks - but I think it will. Will add a pool review with full gear next week. So far I'm impressed. . .even at the price point.
