Greg's Take: If you're in the market for your next race day kicks look no futrher than the X3. This feels like a completely different shoe compared to the prior designs, which has it's pros and cons. The shoe offers quite a bit more pop to your stride but is not the most stable in technical terrain due to limited ankle support and a higher stack height. Full review .
