Shoes now are created in such a way that they are specialized for different people and different events. C-cap (compression molded Eva) is used to create certain spikes, this cushions and creates flexibility in the shoe. On average a running shoe weighs around 160g, this is incredibly light, thus feeling like your not running with shoes on yet still gaining the benefit of spikes.
Starting blocks currently are made of metal, however are reliable in not moving when used, they also have rubber grips on them for the shoes to sit in. Furthermore, the blocks have sensors in them to not only monitor athletes reaction times, but also to create fairness, as, if an athlete reacts faster than one tenth of a second a false start can be called.
