I've started loaning a new pony and I'm finding it very hard to get used to her canter, I keep losing my stirrups! I think part of the reason for this is the stirrups are very bulky and heavy and the treads are quite slippery. I've been looking at some lighter weight ones online, the shires compositi ones get good reviews and I like the look of them but I don't think they're safety stirrups, does anyone have any experience with them? Also there seems to be two types - compositi reflex and compositi premium profile, does anyone have either of these and which are better? Or any other recommendations (under £30)
