English and Western riding aren't that different. Though, in Western riding you wear your stirrups longer.
Here is my dilemma: Every time I ride Western whenever I'm riding at the lope my feet work there way out of the stirrups. It never happens when my stirrups are shorter, and if I try to shorten them my trainer always says, "are you a jockey?". But as soon as they're short that problem goes away and I'm 100% better.
