  • 1/25/2015 Too small for my size 12 feet

    rating star By Tim Y.

    I love the idea of this monofin. It's obviously well made and looks great but it needs to be adjustable around the widest part of the foot. I can barely get my size 12 feet into it. It's painful, like having a clamp on my foot. It's way too tight to use.

    An adjustable, ratcheting strap around the forefoot like the one around the heel would solve the problem.

  • 7/16/2014 Great for dolphin kickers

    rating star By Perry the platypus

    I love this monofin. I've been swimming and swimming competitively for over 10 years but I've never used one but I am a butterfly and underwater dolphin kick addict so when I saw this I was very excited. Although it takes a little getting used to it's awesome to use and just alot of fun and well worth the money if you enjoy swimming like a dolphin.

  • 8/30/2013 I love it

    rating star By Mandy8

    It took me a bit to get used to this from the Tempo FINIS monofin, but I am loving it.  It is a lot bigger. Being a women's size 9.5 my feet were quite cramped in the Tempo, and would even cramp up at times.  I have to have the Rapid on nearly the smallest setting, but my feet have not cramped up nor have the ankle straps slid off as much as they did with the Tempo.  The size difference made me change my stroke a bit, but over all I love it.  My only complaint is that it is that you need some room.  I would recommend this for laps or at least a competition pool with a deep end if you plan to fool around. You get a lot of propulsion, and need to be really careful in small pools or you could bump into walls.

    I have had this for just over two years now, and I have no major complaints other than trying to find a bag to carry it in :)

  • 7/25/2013 Does not fit a size 12 foot

    rating star By David C.

    My size twelve foot will not even come close to getting into the foot compartment, not even a little.

  • 6/26/2013 How strong are you?

    rating star By suzanne l.

    I can swim, thanks to technique and a swim snorkel. But I'm not strong enough to make large movements with the monofin. Others have used my monofin and swim 25 yards under water with one breath. I use two breaths and struggle if I try to move a lot of water. The key to success (for me) is tiny movements: fin up, fin down. Tiny strokes. Then I take one breath per 25 yards. Is the monofin fun? A blast.

    Great for toning core muscles


  • 10/6/2012 Great ab work along with kicks

    rating star By Mic

    In addition to getting the kicks stronger, the kids say that the fin also works the abs.  Not good for flat footed swimmer and would like to have one that fits the smaller foot of the girls.  Size ranges from men's 9 - 13.

  • 10/19/2011 Great but.... boot split

    rating star By Thomas B.

    This fin offers great performance, but after less than a handful of work outs (7-8), the left boot is tearing.  Based on another reviewer with the same problem, I would have to say the quality is lacking. I'm 170 lbs and have a 9.5 shoe size so nothing extraordinary.  This fin should last longer.

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.
