  • 1/6/2018 New Fins

    4 Review Stars By Jon Harms

    Been using for about a week.  Am getting used to them as they are somewhat different from my other fins.  I like them better each day.

  • 8/13/2013 Love these!

    5 Review Stars By PP

    I use these for lap swimming at our local pool.  They are so light that they float on the surface while I am swimming and cause me to keep my legs and body straighter and thus make for a better workout. they seem to strengthen my legs and hip area.  I wear a ladies size 8 and i bought an XS, which was just perfect.
    I look forward to taking them with me when i travel, because they are so light.

    Love these fins but a medium for a women size 9 is very roomy.  Still works though.  Fins really give your legs a better workout.

  • 10/1/2014 Extremely lightweight. True to size.

    5 Review Stars By Geneva

    I decided to try these flippers after undergoing two knee surgeries this year.  I kept reading how lightweight these were and I thought that it would be good for my knee.  You know, not quite so heavy on the knees as other flippers can be.  So I tried them.  And I really like them!  I don't have to use the flipper booties that I always have to wear with heavier flippers.  And they don't cause blisters.  They fit true to size for me.  Great flippers for a great price!  A+A+A+

    5 Review Stars By Bird

    They are a little tight over the top of my foot , but once on, are very comfortable.  You can do any stroke with them but Breast Stroke Kick, is better with out them.  I love them.

  • 8/30/2013 Awesome

    5 Review Stars By Cathy J C.

    These are the most awesome swim fins. I have tried several types of the rubber fins and they have been way to heavy for me. Because of nerve damage from a back injury my legs muscles are weak and the heavier fins just don't work. These are so light and buoyant that your feet stay right up near the surface and I can kick very easily with them.
    I ordered a size large as one of the other reviewers commented that she had size 11 feet (me too) and they fit perfectly. Love, love, love them.

  • 8/20/2017 To large, returning for a smaller size

    4 Review Stars By Joy

    I have not used these yet as I am returning them for a smaller size.  The quality seems good, hopefully I like them once I get the smaller size and begin using them.

  • 11/22/2012 Great training fin

    5 Review Stars By Tom

    I swim 3 times a week doing a varied workout of free, breast and back strokes with and without fins.  Previously, I tried other brands and never found a pair that fit well, had good power and gave my legs the workout I was looking for.  So, I used my old fallback boogie board duck feet (which have great power but are very heavy).  But these Aqua Sphere fins are great.  Super light weight, easy to put on and get off, good power with just the right amount of stiffness.  The only drawback was getting the right size.  My foot is size 11, so I ordered the large size, but they were too tight so I returned them for the extra-large and the fit is much better.
