These are a great pair of flippers. Even though I bought them a size too small they fit well and do not cut into the tops of my toes. They provide excellent resistance for my muscles and give just the right amount of thrust.

I loved these fins while they lasted for my swim workouts. The first pair lasted about 4 workouts, until they ripped at the toe. The second pair lasted only two workouts until they ripped in the same spot as the first, at the toe. These are not durable enough for an intermediate to advanced swimmer who does flip turns, wants to push off the wall, and needs a fin that can take this type of routine. I did not have this problem with zoomers, and like the biofin more, but it is not durable enough.

Comments about Speedo Biofuse Fins:

Enjoyed the fins, while they lasted. Like other reviews on here, one fin tore at the heel, after a couple of months of use. Was going to order another pair on line, however, after reading other reviews, maybe not. I would expect the same occurrence shortly after purchase?

    Comments about Speedo Biofuse Fins:

    I was expecting better. They are heavier than I expected. Need to keep in mind that the XXL are size 13-14. The other Speedo fins I have were XXL but size 12-13. So the sizes are different. They seem well made, but compared to my previous Speedo fins (the regular ones) I think I would rather have my old ones.

    Comments about Speedo Biofuse Fins:

    I love these fins, but like another reviewer I've gone through two finds in no time. They do not last at all (maybe 1month for each pair). On both sets the rubber ripped away from the foot making them unusable. I'm pretty disappointed because when they were new I found them very comfortable and enjoyed training in them.

        I bought a pair of this fin about 3,4 years ago and they are still working great. I use them for my drills training especially for my butter fly stroke. I would recommend this to all swimmers.

                  These are great for my 3-5 mile swims. I have tremendous upper body strength, but needed to find a way to get my lower body worked out. Biofuse fins are the answer. Also helps with your kicking patterns. Great Product!
