I agree with the majority. Pad shape is important, and while there are loads of reasons a pad might slip the fitting issue is very common.
This most often manifests itself as the pad pulling down and back, if the horse is evenly muscled, or back on one side more than the other if the horse is uneven.
A horse should move freely under most of the saddle. What seems to cause the problem is the saddle being tight behind one or both shoulders. As a foreleg stretches forward the pad stays in place but as the shoulder moves back, friction (or skin/muscle bunching in front of the pad) physically forces it back a very small amount. This continues with each stride. Adjust the saddle flock often helps - with a correct width tree - but not always. Horses which are very uneven, needing a lot more flock one side than the other to level the saddle, often still suffer slipping pads. In this instance you need to experiment to find some compromise, unfortunately.
Hope that's some help :)
