I use the product for walking/jogging in the pool.  The weight (1.5 pounds per leg) is a good place to start for me.  Like the fact that it is foam so easy to carry around.  The only drawback is that it is not quite tight enough on my thin ankles and moves up and down slightly when using them.

I use these with my aqua exercise routine for developing stronger legs. You can also use them just to walk in the water. Kinder to your body than working out with weights on land. I have thin ankles and this is the only brand that I can use because the design lets me overlap the cuffs. Hence, it covers a wide range of ankle sizes. Other  ankle products only fit larger ankles. This one fits all sizes. If you have really thick ankles, you can always add a rubber bands to extend it wider.
I''ve owned it for years, but lost one and had to buy another. So I''m glad they make the same style.

Was liking the product until I realized the little black pieces were digging into my large ankles.  Ended up taking the cuffs off prior to completion of my workout.

I tried these out in my acqua zumba class, as the teacher had a pair for me to try.  They feel a little strange at first, but I think that they really help me to put less impact on my knees.  I can now do all the jumps in class without having knee pain and swelling afterwards.  The ankle cuffs don''t keep you from being able to touch the bottom of the pool, so you can still dance your heart out if you want to!  I now have a pair of my own.

Taking water aerobics for a while, I needed extra resistance to move
me forward.   These are great.  Using them for plus size ankles were a little too tight in the beginning, but are stretching comfortably.  Use on my
wrists as well and was surprised at the resistance provided.  Would buy
again.

I use these in my water aerobics class but have only used them a few times. Plan to use them every time so I hope they hold up. Previous ones were held together with Velcro, which did not stand up to the chlorine. I really like this closure system, easy to use and no parts to get lost.
