Moonstar 810s Based on the "STUDEN" jog shoes, which have their roots in the "SC Athletic" shoes popular as school ground shoes, this is an update with a focus on "warmth." In addition to the traditional comfort, this winter limited edition type incorporates a "HEAT LAYER" structure in the insole, which generates heat, improving comfort in the winter. The upper combines corduroy, synthetic leather, and mesh, adding an accent to your feet. It can also be arranged with the included flat shoelaces. With its simple design, these shoes can be worn daily without being restricted by your outfit. I have worn them about 5 times. Thank you for looking.
