The Optimus Prime Climbing Shoe is the fourth installment in the Sharma Signature Series of shoes. Who else better to design a climbing shoe than one of the strongest, most well acclaimed climbers in the world. Designed on a downcamberd last, the Optimus Prime has a deeper fitting heel and much stiffer heel cup than the Optimus.
Designed on a completely different last than any other climbing shoes, the Optimus Prime offers a symetric toe box (rounded toe box). It also has the oval grid pattern rand for added protection and for improved toe hooking while the hook-and-loop fastener maintains the shape for a tight fit.
