Is it really true that 1lb on your shoes = 6lbs on your back?

I recently got a pair of Asolo TPS 535, not sure if I make a mistake getting this shoes? This is my first pair of backpacking boot with full gain leather. They are heavier then regular hiking shoes. My purpose of getting this shoes is for multi day hike out on the back country with 30lbs plus pack. The quality of this shoes is high. Double stitching with thick leather. The sole is stiff yet has enough flex for movement.

My concern is that how will this perform out int he field. With the heavy weight makes me feel fatigue? If you have any experience with this shoes, please do share your experience.

Thanks in advance.
