It's time to replace a pair of Twisted-X boots that have cracked. I decided to try these because someone told me the Ariat version of these boots is better and I really like the Ariat lace-up boots I have. I can definitely say that they have more support and are generally thicker (soles, leather, laces, etc.). I wear them to work everyday and typically have 6000-8000 steps and they are comfortable. However, I found them to be similar to Twisted-X. When running in packed snow or icy areas they tend to be very slippery, but I put on a pair of YakTrax that I previously bought if they are too slippery. I definitely recommend these Spitfire boots.
