  • 10/10/2015 The fins are not the size they say. Dont buy them if you cant try them

    1 Review stars By Capt.Billy

    I paid more for shipping than i paid for the fins. The size on the fins is exactly what i ordered but they don't even fit over my toes. Now i am stuck with these fins that dont fit.

  • 1/3/2017 Not to size is an understatement

    1 Review stars By John B.

    Not to size. I wear a shoe size 9 1/2 to 10 depending upon the shoe. I purchased a ML for shoe sizes 8-10, but these were so small that I would bet someone with a size 9 shoe could not fit into them. They were so tight that I thought the fins pulled my little toe on top of my big toe. The shipping charges I paid exceeded the cost of the fins. Not worth ordering ANYTHING through Swim Outlet that has to do with footwear.

    3 Review stars By conchita parker

    I just order this one recently I have to return them because it was too small.
    I like the product but it was too small. I have to re-order a larger size.

    5 Review stars By Swim Mom

    I ordered a set for me and another. I got a lot of mileage out of these fins! My last set lasted over 3 years and a lot of chlorine.

  • 8/14/2018 Love These Fins

    5 Review stars By LakeSwimmer

    I have tried many fins for lake swimming and these are, by far, the best. They are soft rubber that allow a good kick without slapping the water constantly and they float which is nice when getting in and out of the water. I wear a size 9 shoe and the 10-11 fin fits nicely with a thin Lycra swim sock for blister control.

  • 11/13/2017 A Great Buy

    5 Review stars By Bob Hansz

    While taking a cruise, I am often left in the outfield as the snorkeling companies very rarely have swim fins to fit my large feet. This purchase provided me the opportunity to snorkel for as long as I want without pinched toes and uncomfortable rental gear!!

  • 1/26/2021 Great quality, but.....

    4 Review stars By Ron

    I wear a "true" size 15 and I ordered the MXXL (14-16). Although I was very excited about the quality of the fins, I couldn't even get them on my feet. They were way too small. I am not sure they would have fit a person with a size 14.

  • 8/24/2020 Customizing My Fins

    4 Review stars By Jim

    These fins were actually long enough for my size 15 feet, but the pockets were too tight even for my medium widths, so I cut holes in the rubber on both sides and now they work fine. At 6'4" and 230 lbs. I needed a bit more blade to move me through the water and my long scuba fins don't work at all for swimming laps. These do the job.

  • 3/27/2020 Remember the Otarie?

    5 Review stars By Old Salt

    I really liked the Otarie and these are a direct copy. Or maybe they are the same. Otarie is sea lion in French. I have used numerous different fins and find smaller blades useful but my preference is for these. The UDT duck feet are second in my experience.

    Softer heal pocket and big rigid blade. Excellent. I use them for bodysurfing. The yellow version says they will float but I have not tried them yet (Covid-19 caution and rules).

    5 Review stars By Dave Taylor

    Old line quality U.S. Divers products are always good. I set a "personal best" time
    for 1000 meters, 18:47 in our local pool. Comfortable and ideally fitted.

  • 12/10/2018 Great product!

    5 Review stars By Dave46

    Product performed very well for two weeks I have had it.
    Nice fit, easy to pack, highly visible and floats.
    Reasonable price

    Black and yellow colors bled/overlapped. Don't think the fish cared.

  • 10/21/2018 sea lion peculiar name for this

    5 Review stars By margery

    Love the flexibility and size. Took several wearings in the hot tub to soften and widen the fins to fit my feet.

  • 10/8/2018 Rubber meets the water.

    4 Review stars By Senior Swimmer

    I used to obtain the fins from Sports Authority, but they went out of business. I looked at the U.S. Divers website, but no way to purchase. Thanks.

  • 7/28/2018 Good Fins at Good Price

    5 Review stars By Sugarcane

    I am a men's size 9. The sizing is correct. They have very comfortable foot pockets, and provide plenty of thrust. I use them for dolphin kicking drills and sidestroke practice. They also are fine for freestyle and backstroke practice, and flutter kicking drills.

  • 12/2/2016 Very pleased

    5 Review stars By Pittfan

    I am quite pleased with these fins. The foot pocket is very comfortable, and they actually do seem to float. I wear a size 12-13 shoe depending on the manufacturer (46 Euro) and ordered the XXL. The fit was perfect for my needs.
