How do I know which pad is right for my horse?

Have the horse stand on a pad to see what his/her reaction is.  A horse that walks, kicks the pad out or lifts the hoof and will not weight the hoof is avoiding the pads.  That is not the pad to use at this time.  If the horse stands on the pad and gives any of these or all these signs then this is the right pad: licking, chewing, yawning, won’t give the hoof when asked.  To get the pad simply walk the horse forward.
