The Spriti rules for Dynafit compatible boots
I upgraded from the Scarpa Matrix this year and have found these boots to be a bit stiffer with an improved tongue. I also would prefer a stiffer tongue but for the weight of these boots they have performed well and are supporting enough for my 6'4" 200 pound frame. For a wider foot these boots are a better fit for me over other brands. Be sure to have the liner heat molded and you're set!
