lems -----> Blundstone?

I have primarily worn Lems Boulder boots for years now, my foot absolutely loves them. The one thing I can't stand is how the foam outsole wears down within just a few months. Yes, i've tried the summit and i've seen the new pro, but there's something better about the way the classic waterproof version fits me. I recently popped into REI and decided to try Blundstone after years of fighting against the trend. I thought they were pretty comfortable, and they do seem to last longer than Lems. I am worried about the heel rise/shaft and wondering if anybody on here experienced foot pain when going from Lems to Blundstone.
