These boots are rigid and weight reducing. For me, that means there isn't too much flex like a sneaker but does give you a lighter on your feet feel like a sneaker. Meets my expectations in that department. However, the left boot feels a little tighter on my foot than the right. I could have disproportionate feet or the boots could be a little off. Not a huge deal, I just wear thinner socks to compensate. Aesthetically, I'm impressed with the boot. Would recommend/buy again.

My feet are killing me!

Long story short. I was hired to deploy overseas on short notice. My normal gear was located in a different country so I outfitted myself as best I could, these boots being one item. On day two, my left foot was so crammed in that I actually thought that I was sent mismatched sizes, it wasn't but for the left boot to even fit with some comfortability, I had to pull out the sole pad and even though it helped, my foot feels crammed in. I own a pair of SFBs and even though I wear a size 9R, I ordered a 9.5W based on trying a friend's on and they fit perfectly so I ordered the same size with these. Don't know why Nike can't get sizing correct. To make matters worse, they're stiff and the left boot squeaks like heck. Embarrassing. One nice touch though. There is an elasticized lace keep at the top of the tongue which, I will eventually cut out and sew it on my SFBs because these boots are going in the trash soonest.

I really like these boots, I would recommend ordering a 1/2 size bigger than what you normally wear, I had to return my first pair because they fit too small but I returned and received my 2nd pair without any problems in a timely manner…
