TRANSIRO POWERSTRAP R4 is a triathlon shoe with an extremely quick and intuitive to use, enveloping Velcro closure, ideal for shorter-distance races. For sprint or short distance triathlon formats, where every second shaved off in transition matters, we wanted to deliver a shoe that could offer the fastest and most intuitive closure system possible.
POWERSTRAP
Powerstrap is extremely quick to fasten: simply slide into the shoe, pull and roll out from the transition smoothly. The strap is designed to pull an extended area of the shoe’s upper, so the fit is enveloping and secure, even with a relatively simple system.
To ease transition, the Powerstrap can be locked in the wide open position ready for quick and easy foot entry, while the heel is equipped with a rubberized loop to facilitate setting the shoes ready clipped into the pedals, and easily and quickly pulling your feet into them.
The shoe’s upper construction combines mesh – for superior ventilation – with Microtex, to ensure appropriate foot support in every pedal stroke.
R4 OUTSOLE
The upper is complemented by a moderately stiff R4 outsole, delivering a striking balance between comfort and pedalling efficiency while still providing efficient ventilation for temperature control.

FEEDBACK
Did some research on best Tri shoes as I’d been struggling to get my feet in to the current shoes I had quickly. Absolutely delighted with these, the are so easy to slide feet in to and out of. Hopefully transition times will improve now.

It’s a little too early to really give a rating as we all know it takes time to wear in new shoes. However, so far so good. They're comfortable and breathable. The strap makes it quicker to put on. They do feel a little snug along the sides but again, I’m sure that’s because they are new. Overall hoping I’m happy with them a few weeks from now.

Great entry-level triathlon shoes. Better than a entry-level road shoe on the feel. The strap system allows you to get a nice fitting on the upper part of the feet and the toe box feels good and breaths well.
Fits a bit large on the length.

My third pair of Fizik shoes and I couldn’t be happier. The attention to detail and the small things that have been incorporated into the shoe from their non-triathlon shoes, makes this shoe one of the most comfortable. The power transfer feels much more normal that other Tri shoes I’ve had because of the enclosure system. I have relatively wide feet so finding a shoe that isn’t too narrow has been an issue. I recommend trying these on first as the sizing charts are little funky.

I just received the shoe and have tried it, but haven't raced in it yet. However, I already love it. Lightweight. Feels great. Strap stays open for quick transition and is quick and easy to Velcro shut while feeling secure. Based on reviews I read online I ordered a half size down from what I normally wear (typically US7/EU40 ordered 39.5) and fits great. I would highly recommend and am now looking to convert my road shoes over to Fizik.

Great shoes, comfortable, exactly as advertised. I like the little non-slip dots in the heel cup, the tug loops on the back of the shoe, and of course, they are visually stunning. I am an American female size 10 shoe and the 41 fit me great.

I ordered the 38.5 size where i find the right shoe is slightly smaller (like 3mm) than the left one. Overall, the shoes is comfortable, but be mindful that you better size up a little due to the discrepancy.
