They were wonderful!!!  Helped to make the fins fit so smooth.  A friend recommended these and I'm so glad I took her advice.  I love them!!!

I get blisters when wearing fins, no matter what I do to try to prevent them.  So I use these socks with fins, and I stay blister free.  They are made well and they are comfortable.

Got these as a gift for my husband to go inside his new  zoomer swim fins. They fit snugly, and keep the fins from rubbing on his (wide) feet. He likes them, and they seem to  increase comfort of the fins.

These fin socks are fabulous for saving your feet from blisters from flippers.  I wear a size 8 shoe and bought the small size socks, they are a little snug, but I think the next size up, medium, would be too big.  In the water the socks loosten up a little and fit perfect.  They are so great that I ordered another pair for a friend that swims with me.  I have only worn them a few days, but I am thrilled with them and  hope they last.

They were bought to make a set of fins stay on better and they work great.

I use this with my swim fins to keep blisters from forming on my toes.  They work great.  They are very comfortable, easy to get on and off and they also keep your feet warm.  I bought two pair so I would always have a dry pair.  And they're reversible.
