Spend some time trying on different brands and models to see what fits best.
I tried Nike and had heel lift even with J bars, so I kept looking. Thirtytwo Lashed with fast track lacing worked the best for me. I didn't like the boas I tried because I couldn't tweak it where I needed. The FT lacing system worked better for me.
Go to a good local shop and spend some time with a good boot fitter. Heat molding and inserts like J bars, C bars, and such can make a big difference.
Before I bought this last pair of Nikes I probably tried on 20 pairs of boots. Im sure Ill do the same thing again
I was hoping to narrow it down some before going in but you're right, that's the best way to figure it out.
I am interested in the FT sytem though. Aren't there 4 or 5 'zones' to tighten? Do you have trouble getting enough muscle to pull me tight enough?
