Bought them for two kids. They are like pillows on feet. The lessen the pressure on your extensor tendons on top of foot and facilitate a more natural kick.
I bought these fins for my daughter as the previous ones were cutting into the top of her foot. These fins are much more comfortable than her previous similar fins made of a stiffer material. She reports that she feels like they may generate less power when kicking though. When she tried her old fins after using these for a couple months she stated that the stiffer fins felt heavy. I believe she prefers these DMC fins for comfort and ease of swimming with them.
This short fin fits nicely and is softer, and more flexible. Perfect for longer distance fin swim. If you find other one a bit hard and heavy to handle, this would be good alternative.
