Strengths: These were my first Mizunos after having had 3 pairs of Nike running shoes. Had to buy half a size bigger than usual but comfy straight away and very light.
Weaknesses: Haven't found any yet.
Overall: Light, suportive shoe, impressed with the comfort level. No rubbing or blisters which I expected on changing brands. Able to buy these on the Sweatshop website in their sale for £55, good value for a £90 rrp shoe.
