    I really love this product, the fins fit perfectly and have helped me develop my technique. And super delivery times too!

  • 4 out of 5 Biofuse fins

    Newitts Verified Purchase (13 Jun 2015)

    Great product. Don't be afraid to get the smaller size if undecided as they stretch a little and a tighter fit as always a lot better than a looser fit. I am a size 6 and bought the 4.5-5.5 and they fit like a dream. These are good fins if a little heavy but this just makes them better for training if improving your kick is what you're after. I just bought them for fun use and they're great for that too

    A good training fin. Both of the girls have narrow feet, so I was worried they would slip off, but gheyve been great,

    2nd pair of fins brought from you my grandson has grown out of first pair very good product and also a very good comfortable fit

  • 5 out of 5 Just the kick I needed

    Newitts Verified Purchase (21 Aug 2014)

    My swimming coach asked me to get these fins and even after the first use I found an improvement in my kick when swimming without them. They have helped improve my technique, strength as well as improving the flexibility in my ankles. You do have to persevere as your legs get more tired and I found I needed to really stretch my calves after use.
    I also found that they rubbed the top of my toes and my ankle so I use a small amount of Vaseline in those areas and have had no problems since.  
    I am happy to recommend these fins although having not used any others I can't make a comparison.

    Second lot of fins from newitts. Excellent item at an excellent price. Would highly recommend to other swimmers for pool training.

    Excellent for training. Helps to focus on breathing and arm movement without having to worry about the feet. Very sturdy without being heavy.

  • 5 out of 5 Look like they will do the job

    Newitts Verified Purchase (26 May 2014)

    Unfortunately our local pool won't let me wear fins in the pool so I haven't tested them yet! I bought them to train for a swim around the Greek islands, sot he way things are going I won't know how they work until I get to wear them there. They are shorter in the fin length than I expected, but I'm used to the old fashioned fins. I'm sure they've been ergonomically designed to work the way they should. Feel sturdy and the fit is perfect.

    Fantastic Fins, great in the swimming pool, Super quality. Only negative point is they are not generous on the width so can be tricky to put on.

    Newitts Verified Purchase (17 Mar 2014)

    Bought these for my daughers swimming. I use them when coaching and find them very useful in drills for those who have specific weaknesses in their stroke. Would recommend them

    Newitts Verified Purchase (17 Nov 2013)

    My daughter was thrilled with new fins, fit excellent. Very competitively priced and rapid delivery.Would recommend to a friend. Thanks

  • 5 out of 5 Excellent fins

    Newitts Verified Purchase (10 May 2013)

    Really pleased with these fins, bought for training. Sizing accurate, and heavier weight of the fin keeps legs in the correct position for kick. Very comfortable.
