The echoes of legs allow for faster travel. Used on a horse it would basically create a copy of Sleipnir, but it also allows for doubling destructive output minus weapons. How does having more legs allow for faster travel? It's not moving his body faster, just stepping in the same place twice..

Echo semblances don't suit someone who is all about speed, because a speedster is always wanting to get somewhere faster, while an echo is more about lingering in the past. So someone who dwells in the past a lot, or has regrets about their past, would suit an echo semblance well, but not someone who is all about speed.
