Skippy!, I don't know about you, but I'm finding this fun! Lol.
You are talking about the 'showy' and 'enhanced' Running Walk and Rack. Yes, they look both the same (kinda) in the 'showy' world... but get two regular shod horses, Walker and Racker, and the difference...is huge...
The Walk, flat shod, is much more toned down... the only reason that show Walkers walk such an exagerated walk is because of the weights they wear. (it's ridiculus...)
Here is a picture of a TWH doing a 'real' running walk.
And the Rack, again, you are talking about the show horses Rack... they also wear weights to exagerate their gait. (again...it's ridiculus...)
Here is a picture of a 'real' rack.
(and yeah...for some reason, most people who ride the show Walkers and Rackers heels are almost always 'up' and toes 'down'...it really irks me, even though I have a bad habit of my toes 'down' and heels 'up'...lol.)
And Kiki...I hear ya! Connemara's...never really been around one, so I can't say nothing...but Shetlands (or, as my uncle calls them, Sh!tlands)...ohhh boy...I think they have to be evil because of their size! Those little monsters make me wanna...!
