What is the purpose of the Power Anklet?

Question

It promotes speed while lowering it. Doesn't this counteract itself?

Answer 1

A Pokémon holding this item now gains 8 Speed EVs instead of 4 whenever it gains experience during battle.

The purpose is EV training. This relates to the saying of taking a step back in order to take 2 steps foward.

It doesn't take away any EVs, just lowers speed like an Iron Ball.
