The Nike Zoom Force One X BOA is pretty much the Zoom Force One with Double BOA lacing instead of traditional lace. We are more fond of the traditional lacing system but many will like the easy of entry and crank down ability of the BOA model. The Double BOA is not like traditional lace or speed lace when it comes to adjustability. It shares the middle so you can’t separate them. Some like this because it really cranks down around the ankle but others like me would prefer the ability to keep them separate. Other than that the ride and feel is exactly the same as the Traditional Lace Zoom Force one so you can get the rest of the info on how it rides from the other review. The only real difference is the X BOA version seems to have a more reduced footprint than the lace model.
