Yup, I went for them because I could find detailed measurements for them and couldn’t for many of the alternatives. There are loads of photos and a few videos with me wearing them in my learning journal. I like 'em, they don’t move around and, because they fit right down to the foot, they don’t slip or move around. Looking at my photos maybe I could have gone for the next size up as the back-flap doesn’t quite cover the top of my calf muscle.
I did think them unnecessary after weeks of learning with no apparent impact from the pedals but then when I looked at my pads I could see loads of marks from impacts that I’ve simply never felt. Money well spent
