I looked for something similar at Ducks and couldn’t find any under $50. These are literally identical and so much more affordable. I love how easy it is to switch the weights

I got two pairs of these, one for my ankles and one for my wrists to do wrestling movement drills. These fit my wrists perfectly, but they have about a 3” gap on my ankles. They work fine, I just have to put them on my foot and have the gap over my heel. A good option and well constructed, overall.
