Featuring an innovative Powerstrap closure for ultra-quick transitions, a moderately stiff R4 outsole for efficient pedaling, and a breathable mesh-Microtex upper for optimal ventilation and support. Weighing only 241 grams, it’s designed to keep you light and fast, with a rubberized heel loop to speed up shoe setup on pedals. ## Description T Ransiro Powerstrap R4 is a triathlon shoe with an extremely quick and intuitive to use, wrap, ideal for short distance races. For sprint triathlon sizes or short distance, where every second shaved in transition matters, we wanted to offer a shoe that could offer the fastest and intuitive locking system possible. Powerstrap is extremely quick to clip - simply slide into your shoe, pull and roll out of the transition without any problems. The strap is designed to pull an extended area of the shoe upper, so the fit is snug and secure, even with a relatively simple system. To facilitate the transition, the Powerstrap can be locked in an open position ready for the entrance of the foot quickly and easily, while the heel is equipped with a rubber loop to facilitate the setting of ready-made shoes attached to the pedals and pulling your feet easily and quickly. The upper of the shoe combines mesh - for superior ventilation - with Microtex to ensure adequate support of the foot at every pedal. Review: Hard rough insoles - The shoes are a little big I’d order half a size down and the insoles that they come with are very rough and hard.
