Stride-type runners take a longer stride once they start increasing their speed, but their cadence stays the same. Thanks to an energetic midsole foam and a propulsive carbon plate, runners wearing these shoes will be able to conserve more energy while maintaining their pace at the later stages of the race. Pronation Pronation is part of the natural movement of the human body and refers to the way your foot rolls inward for impact distribution upon landing. Understanding your pronation type can help you find a comfortable running shoe. The METASPEED SKY is made for Neutral.
