With the concept to breed footwork performance through optimal fit, the POWER CUSHION 88 DIAL will receive updates in its tech in preparation for a rolling global release kicking off at the end of January 2022. The 88 DIAL takes inspiration from the POWER CUSHION INFINITY by focusing on optimizing the shoes fit with the application of the BOA Fit System. A better connection with the shoe allows a better connection with the court simply rotate the single-dial BOA Fit System and intricately apply even pressure on the foot for a precise and balanced fit. POWER CUSHION Shock Absorption The YONEX Power Cushion absorbs shock and then reverses the impact energy for smooth transfer into the next movement. Compared with urethane, the YONEX Power Cushion construction provides 3 times more shock-absorbing power. When dropped from 7m above a Power Cushion sheet, an egg will bounce back 4m without damage. POWER CUSHION + A raw egg can be dropped from 12 meters above the POWER CUSHION+ mat, rebounding to a height of 6 meters without breaking.
