Transiro Infinito R1 Knit is a high performance triathlon shoe engineered with an innovative knitted upper for enhanced breathability.

When it came to designing a new premium shoe for our pro triathletes competing in Ironman, we were asked to combine the stiff, race-orientated feel and prime fit of our road shoes with a new design facilitating quick and easy foot entry at transition, and superb comfort for riding without socks. All of this in an extremely breathable, quick-drying construction… challenge accepted.

The result, Transiro Infinito R1 Knit is one of our most advanced designs to date; it utilizes of all Fizik’s most advanced fitting features in a knitted construction that seamlessly integrates ventilation throughout the upper.


Fizik Knit uppers are a cut above traditional woven fabric or microfiber uppers. They are created using electronic knitting machines which accurately link loops of yarn on needles and can seamlessly change the yarn direction of the fabric to create different stitching patterns. This process produces distinct functional zones, with engineered performance in key areas, such as vents and mesh openings for enhanced breathability. The additional water-repellent treatment ensures that the yarn does nor absorb moisture, and in combination with the enhanced ventilation, the upper dries quickly when slipping Transiro Infinito R1 Knit on with dripping wet feet after T1.


To guarantee efficient power transfer to the pedals, targeted areas of heat-fused PU have been integrated to create foot support where athletes need it most. This construction ensures the shoe has superior ventilation and is ultra-lightweight, but with the same support and pedalling efficiency as a traditionally built cycling shoe. The Boa®-powered Volume Control zonal fit is both quick and intuitive and yet provides the locked-in feel triathletes need for a 112-mile ride. The Volume Control system allows a differentiated fit adjustment for the instep and forefoot areas – the shape and volume of which can vary widely between athletes. By controlling two separate Boa® dial closures, triathletes can fine-tune shoe fit to their unique foot shape for customized comfort and support.



The volume of the forefoot area can be controlled via the Infinito, a signature fit adjustment feature. Infinito balances out the tensioning and further eliminates pressure hot spots by using textile webbing in place of plastic lace guides. This closure system acts on a larger area of the shoe’s upper, pulling the eyestays inwards consistently from all directions for a more supportive and comfortable fit.



A customized fit of the plantar arch is provided with the Dynamic Arch Support, a dedicated piece of the shoe’s upper that wraps around the plantar arch, and is adjusted for fit with its own Boa®® dial.



The highly stiff R1 unidirectional full carbon outsole is tuned for the maximum power transfer, with vent openings channelling the airflow through the sole for an efficient temperature control.


The Transiro Infinito R1 Knit features a cushioned flat-seam collar for a smooth sockless foot entry and riding comfort, and are equipped with a rubberized heel loop for setting the shoes on the bike for transition, and easily and quickly pulling your feet into them.

Ich fand die Triathlonschuhe mit Boaverschluss etwas schwierig zum reinkommen. Sie sitzen aber perfekt.

Shoe looks great and seems like it will work well in transition. First wear had a lot of rubbing on ankle, not certain if it will break in a little.

Have taken 3 rides with it so far, very good fit and transfer of power.

Nice shoes and fit well! I like this colours.

These are the most comfortable tri shoes I have ever used (and I've been in the sport 12plus years now)
Verified purchaser | Order code : 108530165
This shoe looks absolutely gorgeous and works perfectly when properly tightened to the feet. However, the Boa release (before dismounting) is not easy and the foot remains stuck inside the shoe. One has to significantly reduce speed and focus on the release process. This could be improved.

Super look. Confortable et qualité au top
Verified purchaser | Order code : 88731956
Look and feel amazing, though not tried on the bike yet. Missing cleats in the purchase. I think, for the price, it should be added in as a plus.
Verified purchaser | Order code : 88116611
Very comfortable shoe. Easy to adjust while riding. Looks great as well!!!
Verified purchaser | Order code : 87548409
Amazing shoes! Very fast transitions from water to bike, easy to slip on tighten and hammer out some heavy watts. Definetly a huge fan of the shoes. Maybe discuss a sponsorship down the road? Worth every penny!
Verified purchaser | Order code : 86920622
Very poor fit. Cause multiple blisters after in 56 miles
Verified purchaser | Order code : 86054857
per ora(usate ancora poco) sembrano perfette

"Sorella gemella" della Infinito R1 Knit con tutti i suoi punti positivi (calzano alla perfezione, si adattano alla mia asimmetria dovuta al collo del piede sinistro più alto di quello destro e sono molto performanti) ma in veste triathlon. Non vedo l'ora di provarla in gara.
Verified purchaser | Order code : 85127129
My husband LOVES them and said they are a perfect fit and feel amazing. Looking forward to making an impact in the 2021 triathlon season.
Verified purchaser | Order code : 77456471
Comfortable and cool looking, but I don’t know that they are worth the price yet but need more time to see how they hold up.
Verified purchaser | Order code : 66493338
One ride. So fare I love them. I like the BOA tightening since I have used it with Shimano for years. It’s even better with the quick release.
Verified purchaser | Order code : 66270283
This shoe is a piece of art, it is so beautifully designed and made. not cheap but worth is. I dod not know I could love a shoe.
Verified purchaser | Order code : 51767605
Stylish and comfortable, feel very supported with this shoe
Verified purchaser | Order code : 49947295
Davvero performanti, il doppio boa consente di avere un'ottima sigillatura del piede alla scarpa ampiamente regolabile. Avevo qualche dubbio sulla calzata veloce in zona cambio ma dopo 2 gare è stato davvero un momento felice anche questo: tutto molto facile e veloce.
