Strengths: Wore these for the first time in the recent snow for a 6 miler along the Thames. Ran on trails, tracks and pavements in dry (off road) and slushy (pavements) snow. Superb grip and not a slip or a slide all the way. These feel really comfy (like slippers compared to my Mudroc 310s).
Weaknesses: Not being waterproof, your feet do get wet. However I'd rather get my feet wet then am able to dry them by body heat than have waterproof/goretext uppers (like the Roclite GTX) that keep any deeper water that goes in over the top trapped next to my toes...
Overall: Snazzy lookin' and comfy lightweight grippy trail shoes. What more can you want?
