I run the 800 and last year as a sophomore in high school I bought a pair of spikes. They were the Saucony Velocities, and they are great. They are slightly worn now, and I was wondering if I should upgrade to a more competitive spike. The Velocities are an entry level spike, and my times are a lot more competitive now. I want to go as fast as I can in the 800.
How much will buying true mid distance spikes help me? For example the Saucony Endorphin MD4s are 3.2 ounces, while the Velocity is over 6 ounces. How much will the weight decrease help me?
How much more aggressive are true mid distance spikes than spikes like the Velocity? I'm not sure how aggressive the velocities were in the first place, so I have no where to start from?
To sum up, I want to know if using spiked geared toward specializing in middle distance will help me drop my times more than a heavier entry level pair of spikes.
