Using a legal amount of NITROFOAM ELITE in the midsole PUMA have given the evoSPEED Forte Nitro Elite a light and responsive wedge of cushioning that works alongside the spoon shaped Carbon Fibre PWRPLATE to give you blistering pace off the blocks and beyond. Beneath that, a full-length Pebax spike plate uses an innovative construction designed to give a better ground contact feel thanks to less layers between the foot and the plate. 6 permanent pins help keep the weight down and are an internationally allowed length for outdoor and indoor tracks and recommended for MONDO type surfaces. A highly breathable upper uses an open woven construction and is infused with carbon fibres to help lock your foot securely into place.
