Developed by Butterfly specifically for indoor table tennis competitions the Butterfly Lezoline Reiss shoes are for beginner and intermedia level players. The Lezoline Reiss table tennis shoes feature the grip, cushioning, and durability necessary for table tennis shoes while enhancing fit to bring comfort too. These mens or womens shoes feature mesh, synthetic fiber, and artificial leather on the upper part of the shoe. The sole is made with rubber and EVA, ethyl vinyl acetate, that aid in the grip and in cushioning and flexibility, respectively. The Butterfly Lezoline Reiss table tennis shoes, ping pong shoes, offer a quality, modern design with angles and curves. They are available in Black, Blue, Navy, or Purple. The Lezoline Reiss shoes also feature the Butterfly Wings logo on the sides in a matching color and laces in matching colors. Please dont step on the heel of the shoe. The heel counter built into the heel part plays the most important role in the shoe's protective function. Because hard materials (resin materials) are used , stepping on the heel part of the shoe may cause deformation, which may tear the inside of the shoe or injure the foot. Also, due to the deformation of the heel counter, it becomes impossible to fully demonstrate the functions of the shoes. Therefore, when wearing shoes, be sure to fully loosen the shoelaces before putting your feet in. If you unconsciously put your foot on the heel repeatedly, the heel counter will deform even with weak pressure. The same goes for taking off your shoes. Once deformed, it cannot be restored, so please be careful.
