I recieved my Sprengers today, and I have to say, they are nice. Felt like my leg wasn't pushing against anything for most of the one hour ride. When something did start aching (normally knees after 20mins) it was my ankles about 50mins into the ride, because I put the stirrups up a hole too much. Did walk trot and canter, and all fine.
I'm sold.
