The Speedo ® Biofuse Fitness Fins are short, dual intensity fins with stiff blades which create maximum resistance in the water.


Strengthen leg muscles
The added resistance increases the workload on your leg muscles which increases strength and endurance.

Increase workout speed
BioFUSE Fitness Fins add extra propulsion to the stroke, which increases speed with minimum effort leaving you free to ingrain correct technique.

Develop ankle mobility
The increased surface created by the BioFUSE Fitness Fins forces ankle extension during kicking, which makes the kick more propulsive and efficient. 

Improve lower body fitness
The added resistance means you burn more calories and increase your fitness levels. 

Want to use training fins to help you work on your propulsive power and ankle flexibility? Our video below will help you get to grips with using fitness fins and features tips from our elite swim coach on training methods and basic techniques.

Customer Reviews for Speedo BioFuse Fitness Fins

  • 5 out of 5 Perfect...

    Newitts Verified Purchase (13 Jul 2016)

    Bought these fins after a free Swimcoach session with Speedo - haven't looked back ! My improved swimming technique, as well as all-round body fitness, continues to go from strength to strength. If you can't access Swimcoach sessions check out Speedo's video tutorials on Youtube.

  • 5 out of 5 Excellent

    Just beginning to realise and appreciate the overall health, fitness and wellbeing benefits of swimming. It takes time for these old body parts to work in new ways - these are just what I need to provide extra propulsion whilst I improve my technique. Oh yes, the price on Newitts - unbelievable and delivery beyond all possible expectations - thank you.

  • 5 out of 5 Flip-tastic

    Newitts Verified Purchase (7 Jun 2016)

    I'm really impressed with the product, they have brought on my leg strength endurace. Definetly worthwhile buying for the serious swimmers.

  • 1 out of 5 not ideal

    Newitts Verified Purchase (22 Mar 2016)

    My 9 year old found the strap around his achilles was not comfortable and the fin length is short, so additional propulsion was not great. Further, the strap snapped after 7 months. As a training fin increasing resistance to strengthen kick they are probably good. For younger swimmers wanting them to lengthen kick and allow focus on arms, a longer fin would be better. Afraid I cannot recommend.

  • 5 out of 5 Great Product

    Newitts Verified Purchase (9 Jun 2015)

    I purchased these fins from Newitts, there was an issue with postage however it was quickly fixed by newitts. the fins themselves are excellent, they are strong and i could really feel the difference using them. good quality and a great price

  • 5 out of 5 Speedo BioFuse Fins

    Newitts Verified Purchase (30 Dec 2014)

    Really enjoying my swim more since purchasing the fins. I was concerned if they would stay on my feet having never used fins before but no problem at all they stay on nicely. The service given by Newitts was 10/10 no issues at all and delivered quickly.

  • 5 out of 5 Excellent fins for training all strokes

    Newitts Verified Purchase (7 Sep 2014)

    Super fins that I use for front crawl, back stroke, butterfly
    strokes and also for kick-only drills. These fins with straps are very comfortable and excellent for improving your swim strokes.

  • 5 out of 5 Can't wait to get in the water!

    Newitts Verified Purchase (6 Jan 2014)

    We bought these short fins to be able to pack in our carry on bags to take on holiday - so will not be using them til the summer. They fit really well, feel comfortable and can't wait to use them for snorkelling rather than the reeally long ones we had in the past - hopefully not have to walk backwards down to the sea!
