Decided to do a review since I was bored.
I couldn't decide between the SIDI Vertigo or the SIDI Cobra's at first. If color is an issue the Cobra comes in different ones but the Vertigo only comes in black. The Vertigo did come with colors, not sure why they stopped selling them.
Being a "novice" boot compared to the Vortice. Reason being is your ankle part slightly bends where as the Vortice or ST it rarely does.
Here is SBTG's video explaining it:
A deal came up and I bought these bad boys lightly used, SIDI Vertigo (Regular not Air) in Red:
They only run half sizes. I wear a 9 US so I went with the 9.5. Theres a little bit of room in there but it's comfortable. The downside is it's a little loose in the heel area. My friend recommended I put some insoles in there to help the problem a bit, still haven't tried it.
I haven't had experience with the Vertigo Air's yet but I read somewhere someone returned them because the Airs were "too cold". I'm fine with the "heat" of the boot. The side vents do work when it's a bit chilly out but I usually keep them open.
These boots are comfortable to me. I was thinking of getting the SIDI Street burners as well for a street boot but I wear these full length boots under my jeans fine. In fact, I can put these boots on faster than sneakers.
The rear calf adjustment helps as well. When I'm sticking my track leathers in the boot I loosen it up and then tighten it. While street riding under my jeans, it helps so that the boot doesn't feel loose around my calves, so it feels secure like it won't fly off.
Being short, the SIDI vertigos won't allow me to move my ankle. Therefore, I have to physically get off the bike to put the kickstand down or up. Not a big deal for the price of having feet.
Picture of how the red looks:
I wore them for 9 hours straight the first day I had them and it was okay. I would prefer not to but it's not unbearable.
Unfortunately, I had the chance to test the boots out at my first trackday. It wasn't a serious accident, minor low side. They held up fine, minor rash on the side of the boot (don't have a picture yet), and my feet had no pain. If I wanted to, I could replace some parts since some of the boot "sliders" are replaceable (being held on by screws).
Overall, I'm glad I invested in SIDI. If I had to, I would purchase them again. They're made for the typical track day rider like myself, and street rider. I've had a lot of people ask me what type of shoes or boots they are, I'm guessing mainly because they're all red and eye catching. You should get the black vertigos if you want to be discreet.
If anyone has any other questions I'll try to hop back on here to answer them.
