Shimano positions the SH-WR83 as an elite racing shoe making it with a very stiff carbon sole and a light weight upper. They feature a light, durable and comfortable synthetic upper that has multiple 3D moisture control mesh panels to help your foot breathe and expel perspiration. A ratcheting buckle and two offset straps help to comfortable wrap your foot with the perfect closure tension.
The full carbon sole gets a 10 out of 10 on Shimano's stiffness scale. Shimano refers to the sole and upper as "Dynalast" meaning it secures the foot into the ideal ergonomic position for a more efficient up stroke as well as the perfect anatomic curve that fits perfectly to the natural curve of the foot. Like most road shoes these days, it is three-hole compatible with a textured area under the cleat to prevent cleat slippage.
