I bought this shoe after using a Vittoria MTB carbon fiber sole for a number of years. While I liked the shoe, it was narrow and my foot isn't, as well as the ratchet release mechanism was difficult to release.
I have a spinal cord injury which has left me with a number of challenges, among then is my right foot drops. I've dealt with it for 25 years which includes riding a recumbent trike instead of a road bike. Recently, I was able to get an ankle-foot orthotic (AFO) to address this condition, even when cycling as it takes up almost no room in a bike shoe or any shoe, for that matter. I use a MTB shoe as they're easier to walk in. My Vittoria's top strap is not long enough to comfortably get around my wide, high instep foot as well as the support going up from the AFO.
This shoe works perfectly. The support which goes across the outside of my foot does not bind and there is room for it and still close the top buckle, though it is close. Also the ratcheting mechanism is easy to release. My left foot is normal and this shoe is the best fitting shoe I've ever worn on it, even before the injury.
I've not given the shoe five stars as the cleat plate is nearly impossible to adjust for and aft or on an angle. That is my only complaint.
For those with wide feet, high insteps or both, this shoe is ideal. THe sole is quite stiff, as I'd expect it to be. The other review mentioned some possible lack of grip in the sole. I've not noticed that myself.
