The Transiro Powerstrap R4 by Fizik
is the brand's first tri shoe to feature the proprietary Powerstrap closure system. This specific component has been raved for its ability to provide a quick and easy adjusting, as well as its ability to stay in a wide-open position ready for foot entry during transitions.
It is recommended for cycling activities wherein every second shaved off significantly matters. Some of the setups this footwear would work well are in sprints and short distance triathlon competitions. If this is right up your alley, then the Fizik Powerstrap R4 should be in your radar.
