I bought a pair of those a few months ago thinking they would be ideal for muni.
I’ll admit that I’ve not actually used them for muni yet, so only have road experience in them, however, I can quite honestly say that all 3 times I’ve worn them, they are the most uncomfortable things I have ever worn.
I think the problem is that the foam is way too hard, so where it’s segmented ‘giraffe-skin stylee’ it tends to make up for the lack of curvature by pinching. And some of those pinches really aren’t very comfortable at all.
I’ve not tried any other hip protection though, so despite them being totally awful, they are the best I’ve come across! Personally I’d just suggest not landing on your hips whenever you come off
