As with so many cycling shoes today the uppers are inflexible and uncomfortable. Otherwise they are very fine shoes that are designed for wider feet. And the fit adjustment is quite precise. I only wish that all of the shoe manufacturers would also make shoes with uppers that have a lot more flexibility. I've been trying to find comfortable shoes for years. And I'm getting tired of trying to find some. I have some 20 some year old Louis Garneau Ergo Air Comp shoes that are almost comfortable. But they are starting to wear out. So I've been looking for something to replace them for several years now. I've tried several different brands. I often do Google searches for comfortable road shoes. Reviewers always comment about how comfortable they are. None of them have been. And my feet are paying the price. I think I will probably wear the LG's out before I will find anything that I'm satisfied with.
For the longest time I wore gravel shoes on my road bike because I was unable to find road shoes that were comfortable to wear for long periods of time. Finally, I found Fizik's Vento carbon shoes and they've been amazing. They are lightweight, have very stiff soles and fit my wide feet incredibly well. The dual boa system is extremely easy to adjust and comfortably tightens the shoe without over compressing in some areas.
The one thing I noticed when I first started riding with these is that the edge of the under flap / tongue is a little stiff and can dig a bit into my foot. However, my shoe fitter suggested that I move my cleats back so I'm not flexing my ankle so much. After a few weeks I've adjusted to a better technique with my ankle and foot and there isn't any more pressure at the top of the ankle. I've also seen that the flap material has broken in and it's softer now as well.
Super light, super cool, for a super wide foot. The BOA placements are some of the best adjusting on any shoe I've had. These are my go-to climbing shoes!
