Fizik says that its new Vento Stabilita Carbon shoe features arch support tech – consisting of an external, separately adjustable strap assembly – provides "tailored support to the plantar fascia [that] minimises unnecessary foot movement” for an improvement in power transfer.
Not long after launching its new Vento Infinito Carbon 2 and Infinito Knit Carbon 2 road shoes, Fizik is at it again with the announcement of another high-end road race shoe. The claim with Fizik’s Vento Stailita Carbon shoe is a bold one. Fizik says that it has come up with a revolutionary design that will “eliminate lost watts” in the pedal stroke, though just how much power will be saved isn’t clear.
The claims centre around the new arch support strap that anchors under the foot in an ‘A’ shape and is then tensioned by the upper Boa Li2 dial via another wide strap.
Fizik says, “When the plantar fascia is properly supported, the medial arch stiffens, allowing for efficient power transfer and the most direct energy delivery from legs to pedals.
“Every useful watt of power generated while cycling is transferred to the bike through the soles of the feet. When the plantar fascia is properly supported, the medial arch stiffens, allowing for efficient power transfer. Because of this, providing adjustable arch support is vital for both comfort and performance in a competitive cycling shoe.”
For the upper, Fizik has used a “resilient polyurethane-laminated material combined over a comfortable mesh.” This, Fizik claims, results in “reduced yield and providing long-lasting foot support where it’s needed most.”
The carbon fibre outsole is, Fizik says, the stiffest in their range and scores a 10 (out of 10) on their stiffness index. The arch support straps wrap under the sole, anchoring mid-way across the foot.
The sole is also claimed to improve airflow and reduce weight via strategic design and internal channelling.
The sole’s design leaves the foot’s arch without any sole underneath it. Firstly, it will be interesting to see how this design impacts on comfort. We’ll be checking for any pressure points created by the foot pressing against the straps. But it also means that this is probably a shoe that is best left for the summer months where the extra ventilation won’t simply provide a hole for any rain to soak your socks.
Fizik’s Volume Control system has also been upgraded, which apparently allows for individual adjustments between the instep and forefoot areas with new, smaller Boa IP2 dials.
At £374.99, the shoes are certainly a premium option and currently, there is just one colourway, though we do like the look of this black and yellow design. Sizes range from EU36 to EU48 with half sizes available between EU37 and EU47. Sound like the shoes for you? They’re available now, but we’ll be asking for a pair to be sent for review should you want to wait for our verdict on this new tech.

Complete nonsense, take it from a shoemaker. you'll gain the same level of arch "support" by wrapping gaffer tape around your instep. Also be careful clipping in, one slip and you'll be slicing fabric against hard plastic
£374.99..... Right.
Cash transfer redesigned.
Oooh, this is very interesting. Mid foot support is a much undervalued aspect of shoe performance, so if this works, then it would be very appealing to me.
My fear, as already highlighted, is that the straps will provide not only support, but pressure points on the mid foot. This pressure would probably be worse than having no support at all.
Fizik's marketing team have completely missed the point however. The idea that a shoe will transfer more power is questionable at best... however, a shoe that optimally supports your foot will enable you to generate more power, or should I say access more of your potential.
I'm talking specifically about resisting torsional flex here. Torsional flex puts strain on your knees and achilles, and so, as you try and push harder that strain gets greater and, to a degree, your body will protect itself from that strain and limit force generation. Reduce that strain and you'll be able to push harder.
If you've got good feet, none of this will matter one jot, but if like me, you've got long, narrow feet with collapsing arches, you could be looking at a 5-10% gain.
