The fins are so light  it''s hard to get traction on kicking sets.

I''m using these fins to train for my first triathlon at a friend''s recommendation.  They are a great training aide.  Not as much propulsion as traditional swim fins but they help develop a more efficient kick and are easier on the legs.

I never used training fins before, so I am still in a period of adjustment,. Nevertheless, I think they are very cool.  Lightweight, easy to put on and take off, comfortable to wear while swimming.  I love the feeling of strength and power when I wear them; beware...the wall comes up faster than without them :) I look forward improvement that using these will bring to my stroke.

These are lightweight fins - great when you have a load of stuff to carry to the pool.  I ordered a bigger size than my normal size since the reviewers suggested that and my fins fit perfectly (I wear women''s size 11 and I got size Large).  I am still not used to these fins when I swim on my side - they are difficult for me to control.  My PT suggested that I need to tighten my lower core more and these fins would be good for that.  (My shoulders are wrecked which is why I swim without using my arms much and use fins to move more quickly.)

The fit is perfect, they do not rub.  They really work the muscles the way I wanted.  I am able to swim much faster and easier.

These are just what I needed; they fit perfectly and are much lighter than other swim fins I have tried.  The contoured shape seems to encourage a more efficient kick.
