The Yonex Power Cushion Lumio Shtluex shoe is a soft fitting shoe for all types of players on all courts. The upper material is made of PU. The midsole is made from EVA and power cushion. It has a endurance rubber outsole The YONEX Power Cushion absorbs shock 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. Given that the POWER CUSHION is so light 1/10 the weight of flexible urethane we are able to fit a lot of POWER CUSHION into one shoe. Not only will you feel the softness and lightness of the shoes, but you will also notice less muscle fatigue after playing tennis.
It's soft, very comfortable. I don't feel like I'm wearing something in my feet. I only concentrate on tennis, meaning it's doing its job. Power cushion I think is making the difference. I can recommend to guys like me who wore adidas tennis shoes basic model for years and want a better shoes.
