Asics Safety Shoes Limited edition CP304 BOA. Color: Fiery Red x Pure Silver Size: 26.5cm The BOA® Fit System (L6 dial) is used for quick and fine adjustments. The design of the sole and the rubber compound have been devised to pursue 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 deterioration by oil. The BOA® Fit System provides a micro-adjustable, precision fit designed to perform in harsh conditions. Brand new, unused.
