I have Sidi Vertibra boots.
Bought them a few years ago when doing my test so can't remember the price. Not long had my first bike so started wearing them more often.
Main grips is the soles are very thin. I could do with some thicker soles to make up for lack of leg length.
Also they squeek wherever I walk. the plastic vertibra system at the back is what makes the squeeking noise with every ankle movement.
Can get uncomfortable if you have to do lots of walking.
