So I bought a pair of the mule Fitflops earlier this year and fell in love. I had been watching these boots for a while, trying to decide if I needed another pair. I finally convinced myself to try them and have not been disappointed. They are super comfy and warm. While I wasn't sure the shoes were actually giving me a workout around the house, when I wore them into campus they were definitely having an impact. They had the look I wanted, with the price I wanted, with a comfort that is unbelievable. You will not be disappointed with this purchase.
