There is no single correct way to run. However there are certain characteristics that seem to be common to most great runners. Striving to run like them will not guarantee you can become a great runner, but it will make it easier to become the best runner you can be.
High stride rate in relation to speed, a tendency to strike the ground on midfoot or forefoot, more time in the air and less ground contact time, knees bent during contact, relaxed and upright upper body.
Four out of five runners overstride, landing their feet ahead of their body, heel-first, causing running injuries. Barefoot runners can’t do it because heel striking is immediately painful, but runners in shoes keep doing it without noticing.
