There is an about a 1.5-size difference between men's and women's sizing. For example, a women’s size 5 is about a grade school size 3.5Y.
The Spider-Man x Air Jordan 1 (GS) “Origin Story” is the kids’ sizing for the Air Jordan 1 celebrating the release of the 2018 Marvel film “Spider-Man: Into the Spider-Verse.” The special edition colorway takes the iconic original “Chicago” colorway worn by the character Miles Morales in the film and adds some Spider-Man specific twists to the design. The red leather panels are covered with a reflective dot pattern to reference Spider-Man’s suit, and the tongue’s “Nike Air” tag is switched to red and blue in a nod to the superhero’s traditional colors. The final modification is an icy clear outsole. The Spider-Man x Air Jordan 1 GS “Origin Story” released on December 14, 2018 to coincide with the release of the film and is now a must-have for sneaker and comic book fans alike.
