webBikeWorld.com: "The styling is typically Sidi and I probably would prefer a black ST Air version, but either way, these are first-rate boots and it just doesn't get much better. If you can swing the cost, this is the boot to have."
SuperStreetBike: "For the rider who wants crazy protection without losing everyday practicality, the ST Air answers the call with protection and style."
TrackDayMag.com: "Well, if the Vortice line weren't so clearly in the lead, we'd have to say that the ST rivals anything else in the market. Fit, comfort, armor and style meet or exceed what you'd expect from a high-end racing boot offered by any other manufacturer."
Motorcyclist: "Sporting street riders who do the occasional track day would do well to consider the Sidi ST's."
RoadRUNNER: "By just looking at the Sidi ST, it is immediately clear this boot is in the business of protection."
