I usually ride with SIDI dominators. However sometimes the trails are really scary and technical and I want to dab. Great for practice on tougher trails.
The shoes are sticky enough, certainly did not feel too much loss of power when climbing. Sole is incredibly sticky, like a climbing shoe.
My only complaint is when I was on an impassable section of South Leaf trail at Skeggs, I slipped on a hill. Wish these had more tired in the heel or something.
Otherwise really comfy shoe.
