The draw: Conforming fit
A neoprene tongue is the most original aspect of the K1. While you may associate neoprene with wetsuits rather than cycling shoes, Fizik selected it for the tongue so water doesn’t seep into the shoe when mounting with wet feet. The downside? Neoprene is less breathable than mesh and the difference is noticeable when riding. The exterior of the shoe—straps and sole—is stiff all around yet the interior is supple and conforming. The K1 fits true to size and has a medium-width arch.
