In what way can you fix crooked toes without surgery.?

Foot deformities. Don't have surgery unless painful, deformed, and not responsive to accommodative shoe wear for 6 months--wide, deep toe box shoes, etc.
Probably cannot. Most toe deformities are a result of heredity and do not correct themselves nor do they correct with splinting, manipulation, or exercises. That being said, surgery to correct the deformity is often very successful, but should only be performed if the deformities are causing pain or affecting normal walking.
