Product Description

The Silicone Biofuse Training Fin is a great choice for the performance and sport swimmer looking for a short blade fin that provides power, speed, and strength. The short blade design balances kicking tempo with a swimmer's arm stroke, but is still long enough to provide added speed and strength building. It utilizes our biofuse dual density technology which combines hard and soft materials in a way that maximizes performance and comfort. You will notice the comfort difference between this fin and our competitor's right away when your foot slips into the soft silicone non chafing contoured foot pocket. But you still have the advantage of the stiff blade for maximum power while training. Sizing may run small, so size up if necessary.

3.0 out of 5 stars Sizing, November 5, 2010

This review is from: Speedo Biofuse Training Fin (Sports)

I haven't bought these yet (so ignore the rating...will rate when I receive them), but was having a hard time finding a sizing chart. With so many comments about sizing difficulties, I figured I needed one before purchase. On the speedo.com site I couldn't find a chart for the Biofuse fins. I finally found a sizing chart on [...] and have no idea as to its accuracy. However, I thought it would be worth posting here:

Speedo Biofuse Fins run quite small with regards to their sizing chart. If you are on the upper end of any size, we recommend sizing up to the next greater size.

XXS - Men's 3-4 Women's 5-5.5
XS - Men's 5-6 Women's 6-7.5
S - Men's 7-8 Women's 8-9.5
M - Men's 8-9 Women's 10-10.5
L - Men's 10-11 Women's 11-13
XL - Men's 11-12
XXL - Men's 12-13

3.0 out of 5 stars Undersized is understatement, September 24, 2010

Several people have indicated that these fins are undersized. This is an understatement. I finally received a pair that seems to fit. As I write this review I am wearing the new pair of fins just received in the mail. Even though they are two sizes over my normal size, they are still slightly tight but reasonably comfortable. With this in mind, I am not writing about the swimming efficiency of the fins, but about their sizing.

My shoe size is normally a 10.5 men. Based on a similar Speedo training fin product this is roughly a large. Unless, I missed something I couldn't find an adequate sizing for the fins on this site. Taking the advice of other reviews, I ordered an XL. They arrived. It was like Cinderella's shoe on everyone else. The lack of fit was obvious. They didn't fit. I sent them back.

As a footnote, be careful what you check as the reason for return. If it is Amazon.com's fault, they will pay for shipping. Totally improper sizing in my humble estimation is their fault. After checking the correct box indicating why I was returning the item, Amazon.com finally agreed we me that it was there fault and paid for the return. (Be forewarned when you check your box).

I reordered an XXL. They arrived today. They fit. As I write this review, my feet are still comfortable in the fins. The lessons learned are as follows....

1. A men's 10.5 shoe size is normally a "L" but is an XXL size in these fins. Use this as a reference for your shoe size.

2. My guess is that if your shoe size is an 11.5 or 12 or greater, you might want to forget about these fins and search for something else. XXL is the largest size.

3. The sizing on the actual fin indicates the following information: XXL is US size 12-13. Wrong!

4.0 out of 5 stars SIZE WAY TOO SMALL, April 21, 2010

I wear a size 7 and ordered the small (size 7-8). There was no way my foot would fit in to this fin. I had to return it and will order a Medium. The quality, though, is very nice.
