Wha was uncomfortable with your Aldens? What lasts were you using? The steel shank actually is more supportive and makes the shoe more stable. It has no effect on sole flex because it is towards the back half of the shoe.
My Stow fit much like TruBalance. Hopefully the Tricker's work out.
I had mostly Barrie last, and couple of TruBalance - I'm not sure why they didn't work for me, but they didn't - I never had a boot or shoe with that effect on my feet. I did have a suede wingtip with a single flex sole - my feet felt ok, but I would get a constant pop when I walked - even after weeks.I gave up on Alden.
