Badminton Power Cushion Cascade Accel. SHBCA1 Yonex 3E Design Purchased about a year ago at a large sports store in Nagoya for around 12,000 yen. Used indoors for 2 months. In my opinion, it's clean, but as it's been stored by an amateur, there are initials written on the right shoe tongue with a marker, along with some scuffs, small scratches, and dirt from use. Those seeking the same level as new products or those who are overly sensitive should refrain from purchasing or do so with caution to avoid any issues. I will do my best to answer any questions about the product, so please feel free to ask in the comments section. I have cleaned the shoes before listing them, so please rest assured. Approved by the Japan Badminton Association Material: Upper: Synthetic fiber Midsole: Synthetic resin Outsole: Rubber sole Power Cushion® Power Cushion is a lightweight shock-absorbing material developed by Yonex. It softens the impact received during landing and converts that energy into the next footwork. Durable Skin Light A thin and strong material. Excellent in lightness, flexibility, and fit. Double Russel Mesh By using mesh for the upper and part of the sole, breathability is improved. It conditions the environment inside the shoes and enables more comfortable play. Toe Assist Shape The toe design eliminates pressure on the big toe, and by enhancing the support of the midfoot and heel, it prevents the foot from slipping inside the shoe, enabling quick footwork without power loss. Round Sole™ The outer circumference of the outsole and the heel have a rounded shape, reducing power loss during natural landing and kicking off, enabling quick and smooth footwork. Radial Blade Sole A new sole shape that promotes pattern deformation. Furthermore, the grip in the vertical, horizontal, and diagonal directions is improved.
