Strengths: Comfortable and hard wearing shoe that I use for training, on road and off road racing. Never given me a problem in over a year, and look as good as new (thanks to my washing machine!)
Weaknesses: Nothing to declare
Overall: I love these shoes. Bought them when I started to run more seriously after a friend recommended them and they do everything I need - training, racing on road and more recently off road. Didn't have noticeably less grip than those wearing trail shoes.
Hard wearing, they still look as good as new and I've never had any problems with them fitting - they're just right.
