  • 11/19/2012 Speedo Optimus Fins - Great product

    Fin sizing reflects the printed size.

    rating star By It''sreallycoolbutIcan''ttellyou

    Awesome fins, great price, can't find them any cheaper. Unfortunately couldn't find them in the 1-3 size for my younger sister. Had to buy a different brand. But when it comes to these fins, they're wonderful, comfortable, obviously great quality. The only thing I'd do is be able to choose the color regardless of size. But still, I'm very satisfied.

    These fins are great! If they're too big, just wear socks with them and they work fine.

    rating star By LoveToSwim

    These fins are great for kick workouts! They really work on getting my ankles more flexible. And, it is fun to fly through the water when I wear them!

    Purchased these for my son for winter swim practices. They fit him perfectly and seem to be well made. Hoping we'll pass them down to my daughter when he outgrows them.

    Ordered a size 7-8 for my 7 1/2 shoe size.  I have worn them comfortably for training and am happy not to have sustained blisters!

  • 8/2/2012 work well

    rating star By northern pufferfish

    Nice to find fins in my size, but the arch area was too low for my high arches - however, since they are rubber rather than plastic, was able to cut that area so they would fit and not tear.  They work very well in the water; too bad the foot box was orange rather than the fin part, they'd have made nice duck feet....

    I use the fins daily for resistance training during my morning swim.  They are comfortable, good style, good size.

  • 6/20/2012 tight fit

    rating star By Jeffrey7459 G.

    I am a 10 1/2 to 11 and these were billed as 10 - 11 but are too snug.  I am use to fins being loose so I looked to order this because of the sizing.  If you are a 10....these would be great

  • 6/17/2012 VERY STIFF

    rating star By Tender Tulip

    I have a narrow foot, but these were extremely tight around the toes and painful on the ankles (very rigid).

  • 6/13/2012 OK

    rating star By clifford b.

    I bought these for swim training because a wanted a shorter pair especially for my backstroke kick. Sizewise they're a little looser than I'd like but my shoe size is on the small size of the size range (11-13) so maybe that's to be expected. It's not too bad but I'd probably think about buying them in a store where you can try them on. In any case my previous experience with SwimOutlet is that they're very good with returns.

    The fins are pretty stiff and so the kicking effort is quite high but being short fins you tend to kick with a better depth and cadence (i.e. shallower and faster - which is what I was looking for) relative to the more "scuba-ish" longer fins Id been using before.

    The appearance of the fins was pretty crappy as they came with some kind of wax all over them (probably mold release wax or something to prevent them drying out). Also the fins look as though the blades were just cut down from longer ones rather than being purpose made. Considering the cost and the brand I expected better.

  • 6/12/2012 Wish I bought brand X

    rating star By sparky

    The Speedo fins have a narrower toe section than the Finis fins and are much too long for training.  They don't allow a full range of motion for the kick (think deep sea fins).  I will have to cut off a few inches of these for them to be useful and am still limited on use due to the narrow fit.  I wouldn't recommend buying these for lap swimming.
