A Power Anklet gives 8 Speed EVs in addition the base EV yield of the Pokémon defeated, while halving the Speed stat of the holder.
A Power Anklet will guarantee the passing down of the holder's Speed IVs to the child when bred. If both parents hold a Power Anklet, one parent will be chosen randomly to pass down its Speed IV. (not available as of Cobblemon 1.4.0)
