Faster in all dimensions, the X Speedportal is designed to help players go beyond their limits and reach uncharted levels of speed. There's improved flexibility in the forefoot with the new Veloxcity Plate, a high-resilience, lightweight bio-based polyamide that maintains propulsion and acceleration performance. A High Speed Stability System provides maximum support through a heel lock and molded fins that secure your heel during explosive downhill and lateral movements. X Speedportal's lightweight Speedskin upper combines the adaptive, supportive fit of Primeknit with a super-thin tactile top layer for an otherworldly mix of comfort and feel on the ball. There's recycled Parley material in the knit, which helps achieve a vegan cleat. With the objective of reducing plastic waste, adidas first partnered with Parley for the Oceans in 2015. Starting with jerseys, adidas has now created a line of cleats to demonstrate a commitment towards a more sustainable planet. Firm ground (FG) outsole and stud layout optimized for use on firm natural grass fields.
