Plate stiffness follows the event, not the price tag
The 60m and 100m use the stiffest plates on the market, full carbon with an aggressive forefoot curve that locks the foot into a sprint-specific angle. The 200m softens that curve slightly. The 400m needs real midfoot flex, since the race is long enough that a rigid sprint plate turns uncomfortable past 200 meters and can change your stride pattern late, right when fatigue is already working against you. Buying a stiff 100m plate for a 400m runner is one of the most common and avoidable mistakes on this list.
