Two Shoe Shapes / One Hoof

Here is an interesting photo I had to take of a shoe I pulled off a horse that someone else had shod.  I thought the foot was a little long in the toe and under run in the heels. But figured it was mainly due because the owner went awhile between shoeings, but after shaping the hoof and then the shoe I realized my shoe, shaped to fit the newly trimmed hoof, was more rounded and not as long as the other. conclusion?!!? get a proper trim first!  But no harm was done so I guess if the shoe fits nail it. yet over the long haul an improperly trimmed hoof may lead to something bad down the trail.
