When ripping around the track at dizzying speeds, a fast spike is a prerequisite for performance. Engineered with a propulsive carbon fiber plate and designed in accordance with World Athletics’ guidelines, the Cielo X MD is geared for middle distances (800m-3K). Combined with HOKA’s lightest performance foam, this responsive race spike delivers a snappy ride in under 4.5 ounces. Why you’ll love it: More cushioning than we’ve ever put in a spike, plus HOKA’s first spike with a carbon fiber plate. It’s all kinds of amazing.
