Almost perfect, one MAJOR flaw
This is my second pair of c4ts/Ry008s (seem to be the same boot, just different name depending on where you buy them) so I'm really familiar with the boot as a whole. If you're looking for lightweight and flexibility? These things can't be beat. Almost the entire upper area of the boot is fabric, which you can see from the photos, so not a lot in terms of protection. But for my needs I'm willing to sacrifice the protection for how light and quick they are. The BIGGEST problem these boots have is the outsole. There is quite literally NO traction or grip once you're on a wet, smooth surface. Sure, you can easily run in these things, can probably even do a marathon, but the second your foot hits a puddle of water on things like tile, linoleum, metal, or even smooth brick/concrete flooring you WILL go flying. I'm not exaggerating or saying be careful, I am careful and mindful. It's just that the grip is so bad that they literally become ice or roller skates at the thought of water. I know the website claims these are oil/slip resistant but I genuinely don't think that's true/an empty promise that doesn't require testing to say. If Rocky can improve the traction on these boots, maybe with more rubber and a lightweight but effective and still flexible lug pattern, I genuinely think these would be almost the perfect boot for my needs, and I'd be a life long customer. Unfortunately the traction is such an issue that I will likely be on the hunt again within the year looking for another lightweight, flexible, and mobile boot. Danner Tachylon is the next one I got my eye on, they're a little heavier but similar design and hopefully the lug pattern helps with slippage.
