Ha Ha don't worry I thought exactly the same. I rode my instructor's horse in my lesson recently and he wears these boots. I spent ages uming and ahhing which way they went. Put them on the way I thought looked better (outer straps facing backwards). Started off in my lesson and my instructor thought it was quite amusing I had put the boots on wrong....oops!!
I can own up to them being new, and they are wrapped up as a pair ! i read the instructions and they said nothing, but i had the whole yard against me ! ha ha wait till i show them the label !
