That is very interesting. Thank you very much!! I am afraid if RF3 PRO may be to stiff.. was it hard to break in? I tried Overtures (48) and they felt like 15, extreemly easy to bend the knee but didn't felt the support. They didn't feel stiff even in hand.But maybe it is just different a one have to get used to that.I found that it was pretty hard to compare support between brands because it depends what fits your foot as well. If the boot is too wide for you or the incorrect shape, it is going to be less supportive than the same or even higher stiffness in a brand that fits your foot well. I tried the Edea Chorus in the correct length and because it was very large around my ankle, it felt like I had no support at all despite the 70 stiffness rating. For me, it was much less supportive than the RF3 Pro which has a 60 rating.
I had a lot of trouble deciding what stiffness to go for in my new boots and went from a Jackson Mystique (15 stiffness rating) for the RF3 Pro (60 stiffness rating) and they're going well so far. Height, weight and skating frequency are also relevant to the decision regarding support ratings
