Strengths: Great fit for people with wide fit (which is why I chose them over the Roclites). Good balance between gripping on rock and gripping in mud.
Weaknesses: 1. The shape of the shoe around the Achilles' tendon is very poor. Most trainers these days have a "V" cut into the Achilles'. But these don't. Having run 6 or 7 short fell races in them this Summer, both my Achilles' tendons are really sore, to the point that I don't dare wear them anymore, and have switched back to my tired old gore-tex-lined Adidas (I can't justify to myself buying another pair to replace my Terroc's so soon, having just shelled out £65 for them only 2 months ago!). I may try inserting an extra insole into them, to elevate the level of my foot, in an attempt to reduce the extent to which they rub on my Achilles'. 2. Very poor stitching quality in the fabric - already seams have split inside the lining of the left shoe. V disappointing, considering the £65 price.
Overall: Disappointing - my first ever pair of fell-running shoes. May switch to Inov-8 Roclites or Montrail Highlanders next time.
