Has anything changed with this boot from last years model? (besides the color) And what has changed if any?
Nope, same exact boot with different colors. Dynafit's new top of the line Zzero 4 boot is the Green Machine TF - it has a new stiffer carbon cuff, sturdier walk mechanism, 10 degrees more stride range, all for 10g less than the C-TF. We should have them in stock soon but until then you can check them out on the Dynafit website:
No major changes other than color. There are some minor changes to the liner, but nothing that affects the fit or performance.
