As I have very flat feet to the point where I have no arch whatsoever I have found that sprinting in sprint spikes allows me to feel taller and run biomechanically more efficient. I have always pole vaulted in Long Jump spikes and was wondering what the pros/cons are to vaulting in sprint spikes and if it is a common occurance eg) achilles problems etc. Looking at my videos, my support foot tends to contact the ground flat with the heel touching the ground for an extended period of time to that desired. Also the support leg has a greater angle about the knee joint than desired. Upon ground contact I do not compress anymore than what happens upon the initial contact so I am not putting the bent leg down to glute/postural weakness.
Any advice would be much appreciated.
