  • 4/15/2012 Great, but fits wrong :(

    4 Review Stars By swimgirl

    I wear a women's 9 shoe size and I ordered a small in the monofin. It was very tight and was not comfortable. A medium would have fit better. Other than that, it's a pretty good piece of practice equipment!

    This monofin works great! It’s comfortable and easy to get in and out of. My shoe size is a 9.5 in women’s, and I ordered a medium and it fits perfectly with extra room to spare! No complaints here!


  • 5/25/2013 Great first monofin or training tool

    5 Review Stars By SeaBear

    For the price, this is a great way to start using a monofin.  The learning curve is much simpler than the larger “pro” models and the price and size makes it approachable.  The blade is super soft as in the entire unit so a serious swimmer maybe better off going with the shooter or trainer model.  It is less intensive on the ankles and knees, and is much easier to put on and off compared to the other finis models.  It is also not sharp and so is much more lane share friendly…as I often bring this along just incase the pool is crowded.  In the ocean it is a blast for body surfing and casual snorkeling.

  • 2/16/2020 Feels a little big

    4 Review Stars By Kitty Goodwin

    I got this to use with my mermaid tail.
    I got the fin that matches my shoe size. It feels a little big when I'm swimming with it and I found out the hard way that you really need diving socks when using any type of fin.
    Other then that it's been a good sturdy fin that does the job.

  • 3/21/2014 order the right size

    5 Review Stars By xlmu

    Ordered a "S" - small for an 11 year old, wearing US women size 8 - medium Nike running sneakers. It felt small when sitting on a chair and sitting in a bathtub full of water. It started to feel it might be the right size only after laying down on the floor for 30 minutes. Do feet change sizes after a hike, a night of sleep or a run? After 2 laps in a SCY pool it felt this monofin had enlarged to a "perfect" size with room to grow, the next size up, "M" - medium will definitely be TOO BIG for swimming. A Medium will not stay on during swimming but it will feel it is the "right" size while sitting on a chair for this particular 8 hours/week swimmer. Please chose your size well for the intended purpose, lawn hopping or swimming, not both, I am afraid. Thanks for your time! P.S. use the updated "size chart" on when ordering, please.

    5 Review Stars By Katie Walker

    Second time I have purchased this. It is less expensive than the others on the market. It’s a mermaid fin for competitive swimmers. It allows for strengthening and coordinating underwater kicks off the walls as well as overall leg/hip coordination. This is the second one I have bought for my son because he didn’t rinse and dry before putting in locker, etc. the other is still functional but has some mold on the straps. I plan to bleach when I have a moment to see if it can still be used.

  • 1/4/2016 Fantastic!

    5 Review Stars By Erica

    My girls received these as gifts for Christmas (ages 10 and 12). They had the best time at the pool testing them out! (Both have size 8 women's shoe) My older daughter wants to wear a pair of short socks to prevent blistering. She's going to test out several option. Super fun purchase!!!
