Barshoes are often perceived as being difficult to fit. I think there are a few basic concepts which help simplify the job. My starting point in fitting barshoes is to shape the shoe to fit the foot the same as I would if it were an open shoe. The variable is simply the length of the bar (how much support I feel is necessary). Think of the two heels of an open shoe as point A and point B. When I determine how much support I want to give, point C would be the end point of the bar. It is then a matter of connecting these points with a radius or even simpler, the straight bar.

The question remaining is how to decide the amount of support. You need to consider the variables such as the intended use of the horse, conformation, pastern angle and possible lameness problems. Your attention and experience in evaluating the variables is going to be a key to your success in applying barshoes. I have some general principles I use.

A.  Let the angle of the hoof and pastern help you decide on the length. You should be working to bring the two angles into alignment.

B.  The more upright the hoof the less bar you need. The more underrun the heels the farther you need to extend the bar.

C.  Use a straight bar for protection, an eggbar for support.

D.  Whenever possible rocker the toe of the shoe and set it back from the toe to enhance the breakover.

E.  On performance horses I never extend the bars beyond the bulbs.

Keep in mind what the horse will be doing. If it is a turnout, you have to be very cautious with the length of the bar. A horse in training kept in a controlled environment can usually handle more extension of the bar. Pay attention to the details and your fit will be much better.
