What Reviewers Say

Size up at least a half size—these shoes run noticeably small and narrow, especially in the toe box. Once the fit is right, the React cushioning delivers excellent comfort and support for all-day wear, walking, hiking, and outdoor work. The lightweight build and carbon shank provide stability without the bulk of traditional boots. Feedback notes initial stiffness that breaks in over time, and traction performs well on dry surfaces but can be slippery when wet.

Cool and stylish but not very strong
Decent support in a lightweight package. Toebox and front edges are not as durable as expected. Just 3 holes of 12 miles total was enough to destroy the front edges and the sole at the toe is separating from the rest of the boot. Probably would not purchase at this price point.

Recommend for hikes, not rucks
I think the silhouette is bit on the bigger side. Other than that, broke in stupid quick… like five miles. Very comfortable lower.

Run VERY small-size up!
As others mentioned. SIZE UP! All my other Nike footwear are size 11 and fit great. I ordered these in 11 and they are AT LEAST 1/2 size too small. Very tight! Good sole and outsole seems durable. Bounties will tell.

BEWARE SIZE UP!!!!!!
I thought I ordered the wrong size or was sent the wrong size. Nope, it was the size I ordered. I can’t wear these things they are at least 1/2 to full size to small. Really wish I didn’t waste my money on these. BEWARE BEFORE BUYING SIZE UP!!!! Nike needs to do better!

Design flaw with glue?
Coming apart where sole meets upper and only with gentle wear, not hiking, running etc.

Great shoe but order up
Got these shoes today. They are great but very stiff. I usually don’t do reviews unless I can add something of value so here it is. ORDER 1/2 size up! They do fit tight. But are very nice and great tred

Horribly small. Like really bad. Bought my normal size and they felt probably a full size too small. Maybe even a size and a half too small. How a major shoe company could make a shoe that wrong just boggles my mind. It’s like nobody at Nike even tried them on. Just said looks good send it.

Great Mid Size Military Boot
Love these shoes. Was looking for a mid size, lightweight waterproof boot for work. Been enjoying these for about 2 months now. Do run a little narrow, so i bought a size up to fit comfortably.

Extremely Comfortable, plus Great Support
One of the most comfortable shoes I have worn in a very long time...Fits true to my "Nike Size." I wear a half size larger in Nike shoes, than every other brand. I ordered my typical Nike size online and they fit great. As long as Nike continues to sell this model; I won't be purchasing anymore Merrell's anytime soon...
