They are not comfortable at all.

You're motivated to get fit. You want a good pair of ankle weights. These are not those.

these are huge on the calfs

Got it to put around ankle to do exercise for my knee. Don't buy!

I wish I had read reviews instead of being in a hurry and going off the high star rating. I bought these to add some toning to my aerobic workouts, but they shift around so much when I move they’d drive me crazy while exercising. The material is also not comfortable against the skin. I’m going to return and look for a well reviewed, slimmer weight.

These are extremely painful!! The sand bags inside are rock hard with no give to them so it feels like your wrapping concrete around your ankle. They don’t mold to your leg at all. The straps are extremely long and a nuisance to put on and take off. I returned them after briefly wearing them twice and realized that was developing tender spots on my ankle bones from these digging in.
