~15 years ago I had a pair of Fox motocross boots. They were very rigid, and seemed very protective as a result. I've had a pair of Sidi Adventures for the past ~6 years. They're definitely less rigid than those old Fox boots, but still quite firm and protective. In the process of getting hit by a car a few years ago, my leg/foot got squished between my bike and the car, and I think it damaged the car more than my foot (foot was fine). I've been wanting some more protective boots for technical riding and had my eye on the Fox Comp 5s - pretty standard entry level motocross boots. They felt like slippers. You could literally fold them in half. Tried on some lower end Alpinestars (Tech 1, 3, and 5), and although they were better than the Fox pair, they were still very soft right out of the box. Now I realize the flexibility allows for better dexterity on the controls, but it seems like they're giving up a lot in the protection area with how flexible they are. I'd love to drop $0.5k on a pair of Sidi Crossfires, but I was hoping to find something with a lot of protection at a more manageable price point. Are slippers all I can expect to find in this range? As a side note, I did try on a pair of O'Neils which seemed to be made out of sheet aluminum, so maybe on the other end of the spectrum.
