Maximum speed, propulsion, and responsiveness – that’s what we’ve engineered in this evoSPEED Tokyo Nitro track and field spike, built for the 400m distance. The track spike features a full-length Pebax fibre plate that’s been specially designed to stabilise the hyper-responsive, insanely lightweight, nitrogen-injected foam midsole, allowing for peak energy transfer from toe off. Providing an extra boost is the lightweight grip with eight permanent Omni-Lyte spike pins on each shoe and a heel pad for secondary traction built into the heel of the outsole plate.
