As far as I am concerned the Driver X is top notch. I have had mine for two years now and I have no complaints. They are actually more comfortable than most of my tennis shoes and I have no problems wearing them all day. I have also never had to worry about cold feet, even in -30 degree days. They maintain traction on any winter surface and are comfortable to hike in. If you've got big feet like me I would suggest getting a binding set that has toe caps, like the Burton Mission, built into the front strap to protect your toes and keep you from dragging. Amazing Boot! Would buy again without a second thought.
