Well it depends, if they felt really good when you tried them on, and you dont mind losing all the best features of the SPK go for it.
But really I would go for the SPK 90 or this years SPK 100. The heat mold liner is a big deal, its much much better then the standard auto fit liner.
Personaly if you have not tried them on and had them fitted, cancel your order and go see a boot fitter. Your feet will thank you
