Incredibly light boot with enough cushion on the soles. I didn't have any break in time with these boots, and so far have been impressed with them. I would not use this boot for field training in the woods, but does great for urban. Only real complaint I have against this boot is the shoe laces which are rounded making them slip my box knot quite often. I have worn various boots from my favorite Rocky SV2's, Danner TFX, Altama, Underarmour (not a fan), and I must say that these C4's are right behind my favorite Rocky SV2's. I recommend not taking these boots off by using your toe and placing in the rear of the ankle due to the chances of ripping the material.
