These ankle weights (they are way too big to be wrist weights) work pretty well for my power-walk regime. I like to feel the burn with these on, they stay pretty securely on and are an ideal amount of weight to carry. My only complaint is that they are not the most comfortable exercising accessory. They kind of pinch at times and sit a bit funny but as long as I wear them over my long pants or have socks under them for my workout then they are absolutely fine. I use them all the time and am glad I purchased them.
