i hesitated a long time between the dead money and Ace of spades, but in the end i went for the AoS...
anyways, the only real difference between the two would be the softer flex in the dead money and some better finishing on the AoS ....
From what i felt in the store the fit was virtually the same, dead money might 've even been better but thats probably because its a softer boot...
The Aos however has been hands down a super comfortable boot, definately the comfiest one i ever had !
the 3 buckle design allows for excellent adjustment, but adjust/putting on/tightening wrongly will definately compromise the fit! so make sure you buckle em correctly, otherwise you're gonna get shinbang or a loose fit ....
also, assuming the shock absorbing in the deadmoney/aos is the same, it's a super dampened boot, i'm always amazed how good they "stomp" on hard ground ....
thats all i can say actually, i think it'll be an awesome boot, i'm definately in love with my AoS boots!
