Question: What size to get for a man's shoe size of 11?
Document: It is a good pair of fins, although it has issues. But I don't think it deserves the price ($34).Pros:1. They propel water well, given its relatively short blade length; In pool swimming I find the water resistance just right for me.2. Good design, material and finish.Cons:1. Sizes run small, XXL is still a bit too small for size 11 feet;2. The sole area is a bit too thick and hence making the fins unnecessarily heavy;3.
The heel part is too high, hurting my feet.Here is the ranking of the five pairs of the swimming fins I have bought and tested recently:1. Aqua Sphere Microfin Fitness Swim Fins, size: 11 - 12 (46-47) (4 stars)2. Head Energy Swim Fin-Size 11-12 (4 stars)3. Speedo Multicolored Short Blade Training Fin, XX-Large (3 stars)4. FINIS Floating Fins,  Black/Navy (Size: 11-13) (2 stars)5.
Construction look pretty good, but they were too small for my 13-14 sized feet. Rubbed raw spots on my toes without water socks. I couldn't even get them on with 2mm water socks. My foot is long and narrow and selection past size 12 isn't plentiful, so I hoped and  these training fins would fit but they have me hoping still.
i bought these for swimming laps and kickboard training. the short blade is a nice departure from the long blades of the past. i feel you work a bit harder with these and i'm good with that. took a few laps to get used to the feeling when i first got them.i have to agree that the sizing is totally off with these. i wear a women's size 7-7.5 wide and the small was too tight for me. i ended up returning the first pair and ordered the medium which fit fine.
I ordered the medium size as other reviewers said they tended to run small (I wear a size 7 shoe). This fin is actually a little too big on me but stays on my feet. Would probably fit better with a swim sock but I don't want to wear one. They certainly give my workout a little extra oomph and makes it easier to swim laps.
They seem to bend more then I like when swimming I like resistance and I don't get much, with them. They fit well.
They are very good! Size Large fits 9,5 women.
I bought this for my wife his to replace a large speedo fins that had cracked after years of use. This one was a size too small so I had to return it.
Really happy with the purchase, I bought it according to the size chart and they fit right. My swimming has improved a lot since I started training with these.
I'm size 8-9. Ordered size 6-7 Size is correct. medium color is sky blue. By using this to improve the lot of my swimming skills, I hope.I am very satisfied.
