General plastic runway using a short nails because the spike bar into the plastic track and then lift knee while they do not feel less obvious, but in the 100 meters in more than 50 years, if every step of the step are subject to such effects is detrimental to
plastic track select short nails
only in the carbon residue before the runway with a longer running spikes because of the carbon residue has played a very loose in order to tread to the effect of drawing is necessary to use spike
As you said there is no scientific method stapler clearly indicate that the individual situation is different soles of the feet hair strength are also different that they can select the new spikes and then practicing on the runway you will see several changes in spikes usually not do special requirements
