Long-term Review: Sidi ST Air bootsĀ
$395 US MSRP
These were sort of the āhigh standardā for street/sport boots in terms of protection and performance at the time of purchase. They were one step/$100 down from Sidiās pro-level race boot Vortice which is worn by some MotoGP riders.Ā
I also previously owned a non-perforated version of the same model (not āAirā) so I can also give some comparisons to that.
Construction: These gunboats are precision gunboats. Surprisingly, they are made in Italy. The cutting, stitching, gluing, molding, nuts and bolts - of which there are many - are assembled flawlessly. Maybe this precision stems from Sidiās experience in pro-level bicycling clogs. Anyway, these are near perfect. I know for a fact that Dainese is not made in Italy anymore, and the Astars boots I have are made in Croatia.Ā
Materials: A lot of the top brands are pushing their synthetic leathers as having advantages over real hide, and the ST is no exception. Personally Iām skeptical of the long-term viability of pleather, but here we are. I donāt know of any pro-level boot made of leather except for Daytona or Kushitani. At least I can say that after a year, the upper shows no sign of degradation with one exception: the pleather piping around the collar rubs on the plastic armor and the finish of the collar has rubbed away. I will monitor this closely and make sure to report of the material fails.
Comfort/Fit: Comfort is highly subjective - if the shoe doesnāt fit, it will not be comfortable. People have a WIDE variety of foot shapes, no pun intended. However, I can tell you I have veryĀ āaverageā shaped feet, with a high arch but not a high instep, medium to slightly wide forefoot. These are comfortably for me but they arenāt exactly a custom fit. Notably, there is no adjustment at all on below the ankle area and the instep is correspondingly voluminous. This is probably intentional - the Vortice features the fussy piano-wire adjustment system that runs all the way down the foot. In order to simplify entry/exit, there is no adjustment here. Still, these have been fine for me for light walking and as much as I would expect from a sporty boot.
