asics Model Number: CP304BOA MAGMA Color: 001 Black x White Size: 28cm Limited edition color!! Brand new, unused! Price is firm due to shipping costs. ----------------Extracted from the manufacturer's website--------------------- The BOA Fit System (L6 dial) allows for quick and fine adjustments to the fit. The design of the sole and the rubber compound have been carefully considered to provide excellent grip. The heel of the midsole is equipped with "GEL," a shock-absorbing material also used in Asics sports shoes, to enhance cushioning. The insole uses a three-dimensional SRB insole that supports the arch of the foot and prevents the heel from rolling inward, reducing the burden on the foot. Oil-resistant rubber is used, which is resistant to degradation by oil. The BOA Fit System provides a micro-adjustable, precision fit designed to perform in harsh conditions.
