  • 10/3/2017 They are great

    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.

    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.

  • 9/19/2017 Neat Product - Not for med-high+ arched feet

    2 Review Stars By OlderD-Swimmer

    I have a med-high to high tarsal bone anatomy.  These seem to be designed for what I would consider a short to maybe short-medium tarsal anatomy.  After wearing for 3+ minutes, the pressure from the foot pocket pressing 'crushing' the tarsals was causing cramping and a bone crushing discomfort. Did not wear in water.  Dry fit with and without Body Glove 3mmsock (NICE sock btw! - Link below unless scrubbed by SO).

    Again, did not wear, but the inner ankle water channel prominence seemed like it would cause problems when kicking from both sides colliding in mid-kick and feet pass each other.

    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.

  • 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.

  • 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+

  • 8/17/2017 Fins Have Changed!

    2 Review Stars By Lap Swimmer

    I have been using this brand and size small fins to swim laps for YEARS .  The latest ones I purchased were heavier and the size was smaller.  I am assuming the manufacturer is different and materials and sizing are different. Was disappointed in weight being heavier and size being smaller since I chose these fins for their lightness and can thus avoid problems with my knees while lap swimming and of course the smaller cut will contribute to blisters. PLEASE BRING BACK OLD FIN SPECIFICS.

    I have size 7.5 women's size feet and my feet are very narrow.  Even the extra small size of these fins were huge on my feet.  My feet swam in them so I didn't.  I had to return them.

  • 4/19/2012 Aqua Sphere Alpha Fins

    5 Review Stars By Phoebe F.

    Be aware that the sizes don't always apply.  My shoe size is 9 which requires a SMALL fin size but I had to return the first shipment as the Small was much too tight.  I exchanged them for a MEDIUM which is fine.  It helps to smear a small amount of soap in the fins to allow for a more comfortable foot insertion.
