Speedo Biofuse Swimming Training Fin Review
I recently tested the Speedo Biofuse Swim Training Fin for AquaGear.
The Speedo Biofuse Training Fin is a small, nimble fin with a foot pocket design.
Fin Sizing
Though I wear a 9 1/2 shoe I have a high arch. I found the 10-11 size to be quite snug and I felt that I was at the limit of what I could do with that size. What am I saying? You may want to go up a size on these particularly if you have a wide foot or high arch. There is a small tab built into the arch that is useful for pulling the foot into the fin.
Fin Feel
Once on, they stayed on quite well though the heel felt a little low in the back. The heel didn’t move around on me, which is a problem I have experienced with some fins. Fins on, I slid into the AquaGear test pool.
Training Fin Thrust
This fin has a small profile and short blade which means it is not going to provide a huge amount of thrust but I don’t look for that in a training fin. I look for a moderate amount of thrust which the Speedo swimming fins provided.
The Speedo Fin is Well Behaved
They were quite stable and tracked well. What do I mean by that? As I kicked I felt I was tracking in a straight line with no need to kick in any way other than my normal kicking pattern. They responded to change in pace rapidly, and felt like an extension of the leg.
I have noticed that some swim training fins work well in a front crawl, but not so well on the back. The Speedo swim fins worked well kicking face up as well as face down.
Swim Fins and Breaststroke
However they didn’t feel comfortable to me during a brief run of breast stroke. The resistance in extending the leg negates the gain from the inward snap. To be fair the only fin I have used that feels like it is doing more good than harm in a frog kick is the AquaSphere Alpha (Zura) training fin. (The Alpha fin is not straight across the blade but rather tapers from inside to out and is very lightweight.)
Speedo Fin Design
In a blue and grey color scheme they are good looking and appear well made of 100% Silicone (latex free) material.
Speedo Swimming Fin Benefits
Swimming fins can strengthen the leg, increase ankle flexibility by extending the flexing of the ankle and provide additional thrust when working on improving your arm stroke or your breathing timing.
The Speedo swim fin provides good value for the recreational or competitive swimmer.
