Fizik R5 Donna Road Shoes
What happens when you forgo kangaroo leather and Microtex for mesh and Microtex? Around a 26 gram weight reduction, actually. This is one of the defining features that separate the Fi'zi:k R3 Donna and the R5 Donna Shoes, and in our opinion, this makes the R5 almost more desirable.
The ratcheting strap is what dictates the entry and exit adjustments. The loading lever is made from aluminum that's been mated to a stainless steel base. It has a double-click adjustment capability with a full-release mechanism at the base of the lever. Together, the three strap system eliminates any internal foot slippage that depreciates your efficiency. To evenly distribute pressure across the top of the foot, Fi'zi:k made the strap dimensions wide. The strap design allows you to easily lengthen or shorten the strap in order to precisely dial-in the volume of the shoe. Also, each strap has been crafted from fully-adjustable length sail cloth in order to bolster durability while maintaining a low overall weight. For an extreme control over volume, or simply to efficiently clean the inside of the shoe, Fi'zi:k designed the tongue pad to be fully-removable.
