I went to store and made a list of stiff boots that i wanted to try, heres my list:
Ride-RFL, Insano Focus
I ended up with the Ride RFL's they aren't the stiffest; the malamutes and the Thraxis were the stiffest, but they were the most comfortable, lightest and had no heel lift. really happy so far with them.
