Being named R1 knit road shoes, I was expecting a very soft upper (slipper like) with a nice stiff sole. The Knit upper is much more supportive than I was expecting and still very comfortable for my feet with massive air flow. The shoes have large air ports on the sole and on an early morning spring ride my feet were very cold. They are perfect for here in Southern California during the summer. Be careful on the sizing. I wear a 9.5 US shoe, a 43.5 Sidi, a 43.5 Shimano. The Fizik size chart said I should wear a 42.5.
So I ordered a 43 - Wrong, I was swimming. Went to a 42 and they fit very nicely. Be careful once you mount cleats they will not take them back (anyone need a 43?).
Product is used (right now) for indoor cycling as it is cold and snowy here in Western Canada, but also will be used for outdoor cycling in the spring, summer and fall months. Like, the construction, fell and fit of the shoe. Don't like - nothing....
I cycle mostly in central Texas and it gets hot. I have the black version. I have used this shoe for several months and have many miles on them. The twin dials allow excellent fit control. The fabric holds up well and cleans up well just wiping it down with a damp rag. The temperature is warming but is still only in the upper 80's. After using these shoes several times in this weather I tried my other pair of cycling shoes that are the usual non-mesh uppers. My feet were notably hotter. Notably. The Fizik knit is very comfortable, the dial in fit is perfect, and the knit breathes very well compared to traditional shoes. These are the best pair of shoes I have owned.
Light, they do breathe through the knit top and has 3 vents on the sole. The twin ratchets are well-placed and do a great job snugging the shoe just right. I have the black with the red underneath, they look great. The only thing I can find fault with is the upper tensioning lace will catch on the foot opening at the top of the shoe. Other than that these are quite awesome. Looking forward to how they perform in the summer here in central Texas.
I wanted to love these shoes. I have a Mt Bike version of this shoe and it is great. Maybe it is my cleat design difference (LOOK vs Shimano) that causes the issue, but my feet still get hot and tired in these shoes. I love the ratchet design and durability and maybe it is just my sensitive feet, but it did not produce a cooler foot.
Living in the deep South of the US, I know hot weather, and this shoe is made to help keep your feet cool. Plenty of ventilation, but even with the knit construction they are very stiff and fit me similar to the Sidi shoes that I have used for years.
