Strengths: Designed for forefoot striking this shoe encourages good form over trails and confidence on hill. It's light weight and responsive.
Weaknesses: I do not find that this shoe provides the grip that you would expect from an off road shoe.
Overall: This shoes appears to have been made on the Lady Issac last (or similar) which is unfortunate as it is narrower than the Gravity and Distance shoes. This is unfortunate as I have wide feet. I trashed the upper in a matter of weeks.
