With each step, the midsole compresses before quickly returning to its original shape to give you an explosive response. The midsole also provides cushioning that relieves joints such as knees and ankles. This helps reduce injuries and prevent fatigue. Ground impacts are also absorbed instantly, meaning no uncomfortable forces are felt by the sole of the foot. Meanwhile, a carbon plate running from the midfoot forward adds structure while guiding the foot and propelling the body forward.
On the outsole, the Metaspeed MD features a six-stud plate, designed to increase grip and support while running. Not only that, but it helps create an advanced level of gip without causing too much resistance with the track surface.
