The adidas Jumpstar Running Spikes are designed for speed and performance in field events like pole vault, triple jump, and long jump. They feature an internal fit system for secure lockdown, ensuring no foot movement within the shoe. The stiff spike plate provides excellent traction for an explosive launch from the blocks. These shoes are made in part with recycled content, contributing to a reduced environmental impact. The upper is made of textile, as is the lining, and the rubber outsole includes a spike plate. Weight is 277g for a UK size 8.5. The shoes have a lace closure with an additional hook-and-loop strap for enhanced fit.
