Long toes only affect the navicular right?
The leg has a series of joints. The metacarpo-phalangeal joint (fetlock), the proximal interphalangeal joint and distal interphalangeal joint (Pastern and coffin). Each one of these joints is a centre of rotation and because of how the digit is not underneath the limb, but in front off, each of these joints is profoundly affected by the distance from its centre of rotation to the point at which the ground acts through the hoof. In the form of the turning force (moment).
An increased turning force must be counteracted by whatever keeps those joints from descending under the load, the tendons AND ligaments.
Hence why long toes affect ALL of the soft tissue structures on the back of the leg. Both tendons and the suspensory!
If you would like this information clarified, explained in simpler terms and would like an introductory lesson in equine digit biomechanics then join myself and The study of the equine hoof on the 3rd Oct at 7pm BST where I will be doing just that.
