Nike Waffle Trainer

Current Price: $610

Size: 9.5

When it comes to Nike running shoes, these are as iconic as it gets — a 36-year-old pair of Waffle Trainers brand-new in the original box. Short of buying Bill Bowerman's waffle iron, this is as close to Nike's roots as you're going to get. (We're pretty sure the waffle iron isn't for sale.)
