Oh durr, didn't even notice the buckles were on the wrong side :]
I don't use bottom straps with mine but they are a nice tight fit and I ride in Ariats with a spur rest.
And to tell you all the truth:
THANK YOU for helping me out. I know everybody has to learn how to use and put on spurs, but I would rather show up to a trail ride with my spurs on right , rather than having the akward moment of showing them off and having everybody 'politely' explain how they go on while they hold back the giggles.
