Popular Model/Series... METASPEED SP Gender... Unisex Type... Spikes Thank you for viewing. This is the METASPEED SP, track and field spikes from Asics. The size is 27.5 cm, and the color is white. I wore them about twice after purchase, but I'm selling them because I bought other spikes. These are all-weather spikes designed for the 100m to 400m hurdles, a high-spec model that combines propulsion from a carbon plate with shock absorption from the FF Turbo cushioning material.
