Fizik Infinito R1 Knit shoes



Awesome performance, awesome comfort, awesome looks... you can almost forget about the awesome price tag too

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

Supremely comfortable and cool, if you know that you'll be in the market for a lightweight and stiff summer shoe in 2019 then Fizik's Infinito R1 Knit should be right in the mix, despite the hefty price tag.

  • Pros: Comfort, fit, breathability, stiffness
  • Cons: Quite absorbent (obviously), a bit heavy, very expensive

We've seen a few knit-based cycling shoes hit the market in the last couple of years, and we've rated a couple highly: the mid-priced Giro Empire E70s and the ultra-premium Scott Road RC Ultimate shoes. Both scored highly in the breathability stakes, while also proving that the far more mouldable nature of a fabric upper section can really improve comfort in pretty much any situation you have in mind. Apart from wet and cold weather... obviously.

That's the downside the Fizik Infinito R1s also share – these shoes are certainly not for winter – but in any other situation they're an absolute dream to wear.

The knit upper is breathable and cool, albeit not as sock-like airy as you might expect. This is my first experience with knit-style shoes, and I have to say I'm slightly surprised that the R1 Knits gave such a well-insulated account of themselves during the autumn season.

I could wear them without toe covers into the low/mid-teens, and only felt too chilly when single figures came along on the temperature gauge. Shoe covers obviously make a huge difference here, but if you then sweat in them a lot or get soaked in a rain shower, the knit gets wet and then you're f… in a whole world of discomfort.

Let's not dwell on that point, though, because for the UK summer – and mild and dry spring and autumn weather too – they're superb. Without feeling overly cool or fragile, they provide plenty of breathability through eight vented sections, perfect for UK temperatures.

I'd heard stories that the R1 Knits can be a little too warm when put into the crucible of European high summer, so without the opportunity to really put this to the test I've used them for particularly grizzly turbo trainer sessions to replicate low-ventilation, warm ambient temperature scenarios.

It's true: they're not that much cooler than my pair of synthetic-upper Sidi Shots, but with a thin pair of technical socks they're hardly stiflingly warm either.

Like the also-top-level, equivalently priced Shots, they're not the lightest either, given that they come in at 679g for the pair. That's in an EU46 – one size higher than the EU45 Shots Dave Arthur tested in 2017, which tipped the scales at 640g – but it's nevertheless a little surprising.

It would seem that some brands are prioritising things other than low weight, and in the Fiziks at least it looks like the beef has gone into the strength of the knit upper and the overall quality.

They really are brilliantly put together, with a tri-zone wire fit system with two Boa dials in place on the flanks of the shoe to help secure the foot in place. Pressure distribution is customisable and ultimately very comfortable, while form fitting to the foot.

It's worth bearing in mind that I have feet on the slightly narrow side, so I can experience some lateral movement in some shoes that don't fasten as securely as some. The R1 Knits, though, allow a really comfortable fit over the foot and without any undue pressure zones, including the heel which isn't too narrow but features little rubber tabs inside to grip your sock gently.

I'm also a fan of the Dynamic Arch Support. There's a little fixed underfoot support in the sole, but the design of the shoe means that, when fastened, the underside of the arch is pulled up a touch into the foot too. The result is a cocoon-like feel around the foot (in tandem with the top tab that 'locks down' the foot), which manages to be supportive without pushing your foot into the upper like some with solid inserts can.

Fizik clearly thinks that this is enough as it doesn't supply replaceable arch supports, and actually I'm inclined to agree on the basis of my experience. Bike fitters might reserve the right to disagree.

The sole is Fizik's top-spec unidirectional carbon model, which is plenty stiff enough for pretty much anyone, full stop. Certainly, it can handle more than I'm capable of putting out as a competently fit sportive cyclist, and lapped up aggressive sprints and climbing around Bath with ease. It has six small vent holes to draw air through, too.

It also offers a surprising amount of comfort. I'd say that my Sidi Shots are marginally stiffer, but they're harsher too. I'd be very happy to spend a summer's day haring around the Somerset Levels in the Fiziks without worrying about numb feet or fatigue.

The biggest sticking point for many (most?) will be cost, although they're not alone at this level. The price matches up to Scott's Road RC Ultimate shoes and Sidi's Shots, and the Sidi Wire 2s aren't far behind. However, Giro's Empire Knit shoes are £150 less, and with that quality Easton EC70 sole they look great value against these, even if they don't have Boa dials.

Value aside, performance-wise there's no doubt in my mind that the R1 Knits are outstanding performers in the right conditions, and while one friend of mine – a Sidi fan – felt it was something akin to heresy, I preferred them over my Shots. They really are just that little bit more comfortable, with a spot-on fit, while meeting pretty much any performance metric you care to throw at them. Except when it comes to the winter, of course.

And I've not even mentioned how great they look. There are also some flashy knit colour designs available too if black isn't your thing. Personally, I like black: they look ultra-premium to go with that ultra-premium price tag, which if you're not worried about having the lightest kicks around, looks like money well spent.

Rate the product for quality of construction:

No fears about the knit upper – it's a visibly high quality construction that (if looked after) should stand the test of time.

Rate the product for performance:

Critics might claim that it's a touch on the warm side in the hottest conditions (surprisingly), but I'd say this points it right at the UK summer market.

Rate the product for durability:

For a knit-based upper, the fabric is very sturdy. Plus, the fittings are all high quality too.

Rate the product for fit:

Just about the best fitting (and therefore comfortable) shoes I've ever worn.

Rate the product for sizing:

Just about perfect in an EU46. Snug, but not uncomfortably so.

Rate the product for weight:

The truth is that 679g is chunky for a pair of shoes in this top price bracket. However, I don't think they suffer for it when it comes to performance.

Rate the product for comfort:

Again, perhaps the most comfortable shoes I can remember wearing. I have gym trainers less comfy!

Rate the product for value:

Hard one. How can something priced at £350 be very good value? The truth is, when you consider it against one rival in particular, it's hard to claim that it is. However, if you have the budget for them, these are top performers and deliver in everything other than winter weather (understandably). You get what you pay for, I think.

How easy is the product to care for? How did it respond to being washed?

Cleaning is advised by wiping with a damp cloth – so that's easy enough.
