New updated strong upper fabric.
Crazy light version of the F2 rubber dob shoe. Precision fit (tight and snug). Same mid sole and out sole with butyl rubber as the Forest 2 but with the Crazy Light upper. NVii use our Hexa fabric in the upper which is a superlight fabric with durability. This is an extreme racing shoe where the weight is critical. In this shoe we combine the perfect fit and grip with a the most lightweight upper you can find on the market. This shoe is also a killer at OCR and trail races where you really need both grip and extreme lightweight shoes.
The Crazy Light F2 comes with a 3-compound mid sole for best cushioning. A softer compound under the heal and a stiffer part in the arch.
