Never owned my own fins before and I took a cue from the other reviewers here and bought a size larger than my feet and these have been a great purchase. Gives your legs a tough workout and with buying one size up they fit perfectly.

the size is slightly larger than my foot which means you dont get the fall workout that one should

I am a USA swimmer and we do alot of kicking drills and the fins work great for making my kick stronger they feel great although first 2 days they were a little uncomfortable until my ankles and feet got used to them now they are awesome!!!!!!

Get the most out of your workout with Speedo Bio Training Fins. These fins increase strength and endurance along with kick speed. Soft on the foot, hard on the legs!

For over a year I have been swimming in the pool with "snorkeling" fins. Finally I found a swim fin both affordable and with an awesome look. They really fit well since I did buy a larger size as suggested. There is little strain on my calfs and ankles and they allow good maneuverablity in the pool. I would highly suggest them for a little extra "kick" in your workout.

These fins are the best for a pool workout for which I use them.
