Spurs are a very popular piece of riding equipment, but they are only one aspect of your overall equestrian education. Proper use of them is critical to properly performing a number of different activities, including driving a horse, training and riding a horse. They should fit just right, like a glove. If they're too loose, they'll fall off; if they're too tight, they won't flex. They should not be so loose that they fall down below the spur ledge onto your heel bases. On the other hand, they shouldn't be so tight that they won't move up and down at all.
