You can count hundrets of things that not exacly are true with irl you know? Someone would be a total idiot to jump from a empire state building with horeshoe in their pocket and think they will survive.Actually, I do kind of agree that the move speed buff on the boots seems off. Owning a pair of steel toed boots IRL, I can confirm that they aren't really the best for running in. Kicking things, on the other hand... Well, what about defence and knockback? There aren't many knockback increasing items in vanilla Terraria, that I can recall.
(Speed buffs, on the other hand, are already fairly common.)
