Strengths: They look good. I have wide feet and feel my toes have more space than the asics. I can just about afford these as I was priced out of the asics nimbus 11.
Weaknesses: they feel very hard and unforgiving inside, my first long run in them was a little painful. Especially as the white decorative line that points towards the toe is harshly stitched in and falls right over the knuckle of the big toe, so i get big pressure points on both feet which i've never had before.
Overall: They will do for the bulk of marathon training but I will definitely have new trainers for the big day, as they are not that good. Won't buy again.
