Adidas adiStar Ultra SL Cycling Shoe

First point to make about these shoes is the weight; they do live up the name. The low weight really did seem to transfer to a smoother and easier pedal stroke at 100rpm. The build quality was very good and the materials including the soft plastic and mesh uppers were very high quality. The shoe is very breathable, maybe too much actually. The carbon sole was surprisingly low profile and I was so much closer to the pedal I could feel it. I actually needed to adjust my seat because of this change. Power transfer is pretty good and the shoe is stiff. I have a regular width high-volume foot and the shoe didn't give me any hot-spots but I did notice areas were the shoe hit my foot where I didn't desire. With the plastic and plastic-mesh upper I don't expect this shoe to form to my feet unfortunately. I can feel a lot of road vibration in this shoe which is a plus and a minus. On area of improvement is the insole, to save weigh I assume a pathetic insole was used, I plan on swapping it out for comfort. Overall I think this is a great shoe but don’t expect it to last more than a couple seasons.
