Coach Mike (SG) 4 Likes : Light and fast shoes, flexible at the right places, quality construction and comfort. Ample heel and toe support. Good ventilation.Dislikes: Grip is not as good with slippery flat surfaces (pot hole cover and cement). The star shaped ‘studs’ at the forefoot will work well on grass and turf surfaces.Caveat: Harder cushioning - good for developed runners.
