In 1989 the Air Span I came & after that, the midsole was made more durable & lightweight, & the trainer changes. The sneaker was originally made for runners. Now with the Air Span II, the shape keeps authentic but Nike did now work more on the everyday’s use of the trainer. So the trainer becomes more a sneaker. In the OG colorway, with the red, black, grey en white combining. Don’t be late & stay up to date. Follow @ Sneakerbaas.
