Product Details

The Fizik women’s R4B Donna Boa Shoes are, essentially, a slightly less “pro” version of the R1B shoes turning cranks in the peloton for 2016. Like its pro-tier counterpart, the R4B has a low-cut ankle profile that allows for unrestricted pedaling motion and helps to trim some grams off the overall weight. Unlike the R1B, the R4B’s outsole is a carbon-injected nylon, and instead of a complete realization of the Volume Control system, the R4B features an asymmetric wrapping closure.
