What makes running shoes bounce? Hey, I'm Richard and I'll explain the chemistry behind it in 60 seconds. Running shoes with Infinity technology not only cushion my steps but also give me back a lot of energy. So bouncy. We call this the rebound effect. It created in the mid sole of the shoe, which uses PSF Infinity particle foam. The secret behind it is air with the right cover. The air in discussion carries me cry easily. Let me show you up close. The form consists of over beats that contain tiny closed air cells. As soon as pressure is exerted on the well it beats, they bounce back extremely well. We produce it from these grains, which, after pretreatment with pressure and heat, pop up like popcorn. Maybe not so tasty, but extremely flexible. This structure ensures robust elasticity, and that's clearly visible when a bouncer metal ball off it. That is.
