I really wanted to love this shoe! It looks great, it’s nice & light, out of the box it looks perfect! However, the reality was different once I tried to put it on. Reviewers had said it runs big, so I only ordered a half size larger than my regular shoe size (I would normally order a full size larger). It didn’t run big, my toes had a little room at the end, I probably could’ve lived with to, but not as much as I like. This is listed as a man’s shoe, I am a woman & I have very narrow feet. I could barely get my foot into this shoe wearing a very thin pair of socks. I’ve never had that problem with any shoe before!! In the end, it looks like a nice shoe, but I don’t know how anyone with normal width feet would even be able to get their foot in!

Purchased these shoes last year, but I have concerns over the long term usability. Sidi doesn't make their road shoes in narrow sizes, so I went with these. They fit nicely and are adjustable while riding. But when the heel plates wear out, there are no replacements like there are for the Sidi shoes.

The heel plates are a hard material and have already worn to the point of the attaching screw starting to wear. Fizik does not make these heel plates available as replacement parts. So what are the options?

I was watching these cycling shoes for quite a while and probably read every review I could find. I've been wearing Giro shoes for many years now and LOVE everything about them, but really liked the look and everything I read about these R1 Infinito. (Didn't need them. Just really wanted them.)



Many of the reviews commented that these run large. I could see that perspective as there was definitely more room in the toe box than cycling shoes that I have had previously. For me, this actually translated to a different fit that I will describe as better. Previous footwear, I have been VERY happy with a snug fit and great sense of security and support. With these new babies, I feel secure and supported, but I don't notice it any more. I have not experienced any slippage or movement inside the shoe. In part, this is due to the additional room in the toe box..., I think. They fit great, I just don't notice it anymore. (Combined with Speedplay Zero pedals, I spend no time thinking about or being reminded of my feet.)



To me, the only drawback is the insole. (Photo attached) At this price point, I would have hoped for something a bit more substantial and probably along the lines of the Giro insole with the customizable arch piece. Creative solution-I took previously mentioned insoles and stacked them on the wafer Fizik insole. Several rides into this new setup and it is pure magic.



If these shoes are on your radar, I would suggest looking into what insole addition or replacement may work for you. (G8 2620 Pro are on the shopping list).



Otherwise, I would highly recommend these shoes if they fit properly to your feet.

I have been trying ALL of these shoes lately, coming off of GIRO NEW Imperial in size 45...straight 45..not half, not near, exactly 45. And I have now attempted to get into the lower priced (even at top level) FIZIK Infinito and Aria - BOTH are a half size bigger and the volume is larger in toe-box - I AM ABSOLUTELY CERTAIN ABOUT THIS - DOWNSIZE BY HALF from your normal Fit. I am saving you alot of frustration. Great overall build quality though, beautiful shoe.

I wear a 9.5 in US and the size chart was spot on. The size chart recommends a 42.5 EU. I ordered the 9 3/4 thinking they would run small, returned them to competitive cyclist for a full refund. The customer service is why I shop at CC. Call them direct for the return label. FYI..I do not have a wide foot, no arch problems. I purchased these shoes because of the BOA closures and the location of such (sides). No review required, it’s a quality well priced cycling shoe.

Very nice shoe. Wanted Fizik shoes for a long time so I finally popped for them. I am a long time Sidi person and just wanted to make a switch. Wear 43.5 in Sidi and ordered 43 Fizik, length seemed identical. Problem was this: narrow in the forefoot area and toe area was restrictive. Boa closure is fine, the way the shoe wraps around is nice, no bite, just secure. Very stiff sole. I am 57 and as we age the old feet spread out - I always had narrow feet, not any more. So if you're narrow and don't need a lot of room for toes, perfect. I say true to size, but run narrow. I will say, CompCyclist was a life saver in letting me return them after riding in them, 30 day fit guarantee. That's worth a lot in my book.

I am 66 year old, 5'5", 138 pounds and riding high end road bikes for 40+ years. Preference is more for climbing. I am not a Clydesdale. I needed new road shoes. I usually wear a size 42 road shoe, 42 running shoe or size 9 in Nike and Mizuno. Dress shoes are usually size 8.5 and often narrow. My instep is low and high arches. I opted for Fizik R1 Infinito because of:
1) narrow last
2) Boa closure system
I have used these for about 8 rides from 20-45 miles each. Overall the impressions are these are a very good riding shoe. More specifically for fit and feel:
*very light weight (plenty of web sites to discuss weight weeny stuff)
*Boa system works very well: figure 8 front Boa closure creates glove like fit and no pressure points
*Top Boa is equally comfortable
*High quality upper and carbon fiber sole
*Extremely stiff sole but comfortable because of "glove like" upper
*I selected a 41.5 size and this is perfect; a 42 would have been too large
*Toe box height is more than adequate
The Ride:
*Similar to light weight wheels, light shoes assist with quick "spin up" and acceleration; R1 Infinito are great
*Smoothness of the pedal stroke is very noticeable; likely because of the glove fit without any pressure points, combined with stiff sole
*Since climbing is my preference, I am pleased to report these are excellent climbing shoes
*Energy transfer is extremely efficient
Side notes:
The factory insole is nice quality but did not work for my high arch and low instep. I replaced with Superfeet Green insole (as with all my athletic shoes). The combination of the Boa system, the upper shoe design and the Superfeet create a long distance comfort with high performance paybacks.
