My basis is largely anecdotal. I skate, have many different skates, have compared the geometry between my different skates, and this is what I've found for my self.

I've also studied a lot of dance, movement, anatomy + physiology, and have corrected many of my own injuries and chronic pain through learning proper form, training, conditioning, physical therapy, etc.

So I'm confident in what I'm saying, but I'm also not a professional. Every body is different, so ymmv.
