To save weight on heavy spike holders, the PUMA Evospeed Tokyo Future features 8 permanent 7mm spikes for the perfect traction to let you put your power down on the track. Placed within the ¾ length propulsion plate you get extra speed too. Talking of speed, a full-length carbon plate sets you up for powerful, efficient strides and record times. Sitting closer to the ground, you get better feedback through each stride. A locked in fit comes through the MATRYXMicro upper which uses seamless, lightweight materials, with carbon fibre threads for a powerful hold.
