  • 7/28/2020 Great fit and overall feel

    5 Review Stars By Liz Talya

    Our 9 year old is happy with her new fins-only drawback is having to share them with her sister as size 5-7 has not been available since early July, and Summer is ticking away. We/they miss their swimming relay competitions with those TYR fins!

  • 1/17/2013 Great fins for swimmers and cross trainers

    5 Review Stars By Sam

    I was a competative swimmer my whole life, swam at the Div1 level in college. I prefer a stiffer feel to fins and these provide that, the Speedos are just a bit too flexible in my opinion. Rubber around the feet doesn't break over time, they give a great feel to the water and how your legs and body rotation are affecting your stroke and kicks. Great price too.

  • 6/29/2017 like wearing lead boots hard to drive

    1 Review Stars By Russell

    I wanted to purchase TYR Split Fins. I purchased TYR Split Fins several years ago and they are wearing out. I couldn't find the TYR Split Fins, so I ordered the TYR Flex Swim Fins. There is no Flex in these TYR Flex fins, they are heavy and hard to drive in the water. Very disappointed that TYR doesn't make the Spilt Fin any more. The Split Fins were much lighter and easier to drive in the water than these Flex Fins. I sent the Flex Fins back.


  • 6/16/2020 Way too big and long

    3 Review Stars By Catherine T.

    I ordered these in a medium as that’s what I thought would be best after reading the reviews.. they were huge in the length and foot size. I wear a women’s 8.5.
    I returned them and ordered another pair of Finis fins which fit fine in a medium

  • 10/2/2014 Nice fins but run narrow

    4 Review Stars By Theresa L.

    I bought these to replace a pair of Kiefer fins but these are really narrow. I don't have really wide feet - never order a wide shoe - but my feet are not long and narrow.  I wear a women's size 9 medium width and I ordered the medium (red/black) fin. If you don't have narrow feet then order up one size at least.
    The fins are a really nice quality and would be fantastic if they fit.

    If you're looking for a firm long fin - this is the best one for the $$$

    I wear a 10.5 and the 9-11 fit perfectly!

  • 9/28/2016 Great training aid

    5 Review Stars By Seb

    I had never thought of using fins for swim training until now. These are easy to carry, fit well, are comfortable, do not rub against anything, and are a good way to add resistance to your kick training and free style. Mixing up the workout, sometimes going with, sometimes without. It feels like legs are getting stronger and more coordinated.
