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.

Expensive, yes. Quality, yes. Buy again, yes.

I debated about buying inserts for these shoes, but decided I wanted the arch support. I'm loosing the ventilation but can rectify that by punching holes in my inserts lol. Beyond that, everything else about this product screams quality. and yes you do get what you pay for. I waiting a month or so to see if the prices on these would drop. they did. I ended up getting them about $150 less than they were marked for when I first started watching them. I suggest waiting a while to see if the same can happen for you.

This is my first pair of cycling shoes. So far, I absolutely love them. The fit of the shoe is excellent, the straps are perfect for getting them on quickly but securely. The materials used feel very luxurious (especially the heel loop). One thing that I will warn is that the front of your shoe will get dirty (the pure white is basically asking for it) from kicking over the clip every time you need to re-mount after stopping at an intersection.

Perfect gravel and MTB racing shoe. Last is a good medium width, material is soft and durable. Sheds dirt and grime and has started bright white. Power transmission is excellent without being punishing. This is a higher volume shoe that leaves plenty of room for orthotics or footbeds. Lugs are grippy without being heavy and seem to be wearing well despite a fair amount of walking on the gravel bike through super technical sections.

An amazing pair of shoes. Very comfortable for a Sprint Triathlon.
The locking system is very well desingned.
I wear them without any trouble in a 37 kms ride (a rare exception for a Sprint Triathlon) without socks and they were flawless along the ride with minor adjustments depending on the ride segment
They look amazing and give the instant impression of a good quality shoes.
Definitely, I would recommend this pair of shoes.
Plus, the price seemed pretty good for me.
Go for them, you won't regret it!

Amazing shoe! All of the support you would expect in a $300 road shoe, breathable yet durable upper with he expected fast close of a tri shoe. When Velcro is undone there is a large opening for your foot, and with one motion you are secured into the shoe and rolling. Interesting, fi’zi:k put little gripper bubbles in the back of the heel cup of the shoe. I ride with socks, but wonder it they would bug me if I were sock-less...

Beautiful shoe (if you are into Fizik's more restrained elegance).
Fit is per usual Fizik for the last 5 years 46.5~12US.

Been doing spin class in these. No road riding yet. Light. Comfortable. Easy on easy of. I have a question on how long the velcro flaps will last. I needed sole inserts

First time to wear Fiziks and love them! Super light weight and comfortable. Thanks Roy for packing my shoes with
