Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example: I've read this book with much expectation, it was very boring all through out the book
Solution is here: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this: These are really good shoes. Great look. Good comfort. No break-in. Very sturdily built. Good price. True to size. The only thing is that, for me, these may not be for general wear. They don't breathe at all (since they are waterproof) and can get a little sweaty and uncomfortable if you are indoors for a while. Driving with these shoes has been a little difficult because there is less leeway for the ankle to move, or rather, it takes some getting used to. I am thinking I should have really bought the "Low WP" version.
Solution:
Positive
