  • 7/13/2012 works ok

    rating star By stephen

    they work fine but I think just getting a pair of regular fins, (lots cheaper) and just dolphin kicking works almost as well.

  • 2/17/2015 Never Buy It

    rating star By Nick

    Absolutely horrible. I'm an 18 year old guy who got swindled into buying this by the crook that designed it when visiting my club team. I would give it a 0/5 if that was possible

  • 4/7/2014 Very, Very narrow

    rating star By Elizabeth H.

    I had to return the monofin because it was much too narrow for my feet - I could only get it on with socks, and even then, it hurt because it squeezed my feet too much. If you have somewhat wider feet, I would suggest getting a size up. I'm going to try that and hope it helps!

  • 3/21/2014 order the right size

    rating star 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.

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

    rating star 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.

  • 8/23/2012 Very Cool! Great Price!

    rating star By Torie

    These are a great price compared to other monofins on the market. This fin is perfect for making a swimmer dolfin kick from the core instead of their knees. Nice!

    rating star By Sarah C.

    The only negative thing I have to say is that it STINKS when you take it out of the package for a good month. After that, its fine.

    The fin works well and fits well but can't seem to get rid of the horrible rubber smell

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

    rating star 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!

Founded in 1993, FINIS provides highly technical competition suits, training equipment, child water-safety products and high end goggles. Their very popular SwiMP3 water-proof digital media player is revolutionary in its streamlined design, enabling a swimmer to listen to music while practicing laps and other exercises in the pool.
