Describe them to your partner and how useful they are in life today. S1: Adidas 1 is the thinking shoes with a builtin microprocessor that decides how soft or firm the wearer needs the support. It has been chosen by Popular Science magazine as the best recreation invention of 2020. It is very fortable to wear it all day without worrying about your toes being hurt and you can adjust the height and stiffness according to your demands whenever you want and wherever you go.
