Speedo Biofuse Training Fin
The fins help strengthen leg muscles and kicks - a definite must if wanting to not only get in shape and tone muscles, but helps empower kicks during swim practice and drills to get the best potential in meets.

Fit and weight of Biofuse Training Fin
I use the fins in training swim sessions. I ordered the small but thought they fit too tightly - I then returned and received the med fins. They are a bit too sloppy. I normally wear a size 8 womens. The other problem is that the toe region of the fin really rubs on the tops of your feet and it is very unforgiving - need time to toughen up the toes to use these. The rubber really should be softer and less heavy in this area.
Fit: Feels too big
These fins are great
These fins fit great, and are very comfortable to wear. I am very satisfied.
Good Training Fin
The fit on this training fin was true to size and required no modification. Good overall training fin, no slippage, easy to slip on. Fin shipped though was a different color than what was ordered.
This is a heavy fin. I'm 50 an above average swimmer but not former collegiate. This fin is flexible on the heel and very heavy from the arch forward. I have difficulty "driving" this fin. IMO you would have to be a strong kicker and wanting to work on kicking for a sprint to use this fin.Sizing went to being larger than expected.
Outstanding training fins
Bought pair five years ago. Daily workouts in both a cold chlorine pool, and a "warm" bromide pool. The fins including foot seem as supple and intact as when I bought them. Neutral direction. No problem with knees, etc. Heavy, and stiff blades, but they are training fins. I'd also use these for body surfing and shallow snorkeling. Various sizes. You want the size that's a little snug, not loose in the water. I don't think Speedo is going to get rich on these ... as they don't seem to wear out or deteriorate ;-}
My son is on a swim team these DID NOT work for him at all as they are way too heavy and they run very wide so no I would never get this pair again. Luckily swimoutlet is great with us returning things. They are super efficient.
Go down one size from the shoe size you wear. For example I wear shoe size 12.5 and went down to the 11 - 12 size. I am very pleased with this purchase after having to return many poor fitting fins. While these are a pricier pair of fins they are worth the money for the good fin. Also, I really like the blade length of these fins; long enough to boost your propulsion, yet short enough to let you keep a realistic kick tempo.
Finally a set of fins that fit! I have what I would describe as "normal" size 13 feet (13E) but have had trouble finding fins that don't bunch up my toes or create blisters. Also...I really like the elasticity of the boot. Just enough to make it an easy pull on or off, but without so much elasticity that they feel loose. The "pull tabs" also make it easy to get on just right. A very good design.
Speedo Biofuse Training Fin
Use: Masters Swim workouts.The fins appear well constructed but are stiffer and heavier than I expected. My major complaint is that the edge of the heel section chafes and irritates the back of my ankle. Unless I modify them or use a light bootie, they will be unusable for me. My last fins (BetterTimes) were substantially more comfortable.
