Comments about Speedo Adult Trialon Rubber Swim Fin:

I am an older occasional swimmer and rely upon these fins to provide additional power in the water. I bought a size 10/11. I am a women's size 11. The fins fit perfectly.

Excellent design and function. My five-year old put them on and they worked perfectly for him the first time. His swimming teacher was pleased as well. As he grows I plan to replace them with the same fin, again and again.
