I am not 100% sure whether or nor cooper infused fabrics work or not. I don't know if the solid bracelets do anything either. That being said, I do know socks. These are good general purpose athletic socks in my opinion. They are quite thick - that will be either a huge bonus or a negative depending on what your using them for. They're thick and provide excellent cushioning for running, walking and, for me, jumping rope. They fit well and don't slip when on. Some may find them too thick, especially in the hot summer months. Or, they may find them too thick if your shoes are a tight fit. For me, I am fine with them and would rather have the extra cushioning when working out. Overall, I am really happy with them.
