Given the task definition and input, reply with output. Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

I'd ordered these boots based on decent reviews and price. I rarely return purchases to Amazon but I did return these. The boots were fairly heavy, stiff and narrow. I get that new boots will be stiff but both the uppers and lowers were too stiff for me. I returned them and bought Adidas boots with Gore Tex uppers which were much more comfortable, flexible and light with good sole traction.
Negative
