Did you get use to it? Do you like the rocker? Sounds just like what I’m dealing with
I have come to appreciate it very much. Like I said the lowa I had were very stiff and flat, so when walking on flatter ground it was really hard push off the front of your foot and engaging your calf muscles. Not sure where you are gonna go hiking but where I've been in AK sheep hunting there is always hiking on flatter ground involved at some point.
The rocker on the crispis made it way better for me. When walking in those the rocker allows your feet too roll over to the front of you foot when pushing off. Making it more natural movement.
I think you will get used to it. Also like other ppl mentioned if these are your first mountain boots then you may not be used to a stiffer boot that some ppl prefer on the mountains.
I looked up the Kenai and they are rated at 3 stiffness on blackovis. Regular briksdals are a 4, I sent those back cause I didn't think they were not stiff enough. The briksdals SF are a 5 believe and yet they to me are not as stiff as the tibets I used to have.
But I think it has alot to do with what you like and prefer. Also how much you weigh and how much your pack weighs.
A side note, yes the insoles in crispis are junk and I would change them to superfeet or any other insoles of your liking. They will not help with the sensation you are feeling right now. They will however support your arch better which is nice when carrying a heavy pack.
Like somebody else suggested. If you have the option of going to a store and testing boots out it is by far the best way to go about it.
